They were 8 years old at that time. Mitsuru was a clueless kid who didn't like to socialize not until Izumi found him. Izumi's warm and gentle smile melted his heart away. His long winter came to an end when Izumi brought spring into his life.

His mother was a nurse before. That's how she met his father, Aizen, a businessman. He got into a car accident and was taken to the hospital. Mitsuru's mother, Sakura, was the attending nurse at that time. Shortly, they became friends. From friends to lovers, and from that raging and passionate love, Mitsuru came into existence. Two years later, his mother became infertile because her ovary had some cyst. Thankfully, it was treated, but they will never have a second child. Thus, Mitsuru is an only child.

The immigration approved the naturalization of Sakura, and she became a Japanese citizen. She lived with Goro, her father-in-law, inside the Kurosawa estate. Sakura's father-in-law came from a branch family, and there came a time that Aizen decided to live outside the estate. The place was secluded before many people started to move in. This includes the family of Haruki and Izumi.

Mitsuru was reading manga in his window seat when a new neighbor moved in. He looked at the window to see who they were. Apparently, they are from the head family of Ishikawa, and what's surprising is that their child is half-Japanese like him. It was snowing that time. Their child looked at his window, and he saw Mitsuru. He saw his smile, and as that child waves his hand to him, Mitsuru closed the window on impulse. He didn't know how to interact with other children at that time.

Weeks later, the neighbor's child visited their place, and he said he wanted to play with Mitsuru. He was still a bit shy at that time. His mother said he should play with him since I never got the chance to have a sibling. He also told him that she and Izumi's father have been friends since middle school.

"Hello! My name is Izumi! What's your name?" said the child.

"M-Mitsuru." He replied with a soft, shy, and low sound. When he took his hand and pulled him outside, Mitsuru felt like a bird that was freed from a suffocating cage. No matter how many or what material things his parents gave him, it is not comparable to what I have now. He always dreamed of having a sibling, and now he has one. They are about the same age, but Mitsuru's body broader than him. Izumi looked like a bamboo stick then. Months later, Haruki and his cousin, Megumi, moved into our neighborhood, and we also became friends.

Mitsuru read a manga where two people got married. He understood what marriage meant at a young age. He felt a strong urge to marry Izumi, but he saw him as a brother, and his mother told him that when siblings marry, they will be cursed. This is called sukob in his mother's culture. Mitsuru didn't believe it. But there came a reason why he could not marry him. Himself. He cannot stand Izumi being hurt because of him. When they were at the hospital because of that incident, Haruki, Megumi, and Mitsuru saw him crying and his father hugging him. It was the first time they had seen him cry. Unfortunate events continue as something happened unforeseen and Megumi had to leave Haruki's side.

He was supposed to protect Mitsuru, but he could not due to his body. He was often bullied for being girly and weak. Even though Izumi effortlessly fought back, Mitsuru helped him stand up against the bully since he has a large body. Since then, it was he who protected Izumi from those bullies. But after that, Izumi became silent towards everyone except Mitsuru and Haruki. Because of that, Mitsuru decided to enter a martial arts club once he reached middle school to protect him.

They became middle school students and didn't have much time to spend with the two due to his club. One day, he decided to sneak into Izumi's bedroom; Haruki also came. To their surprise, he was reading a BL manga. Mitsuru burst out with laughter that was filled with mixed emotions. He told him that he would not let his secret out. Haruki comforted him, and after that, he laughed at him because Haruki reads BL manga too.

He realized that he did not see him as a brother anymore. He loves him. But when he confesses, will he accept him? Will he reject him? Then, Mitsuru realized, it would be hard for him to say yes to him. He tried to find a way to get rid of this feeling. When they started high school, Haruki and Izumi decided to enter a martial arts club with him. He continued dating girls and having sex with them. But it does not affect him. Luckily, he got no single girl pregnant. He also knew what he was doing was wrong. Still, biologically speaking, he was at the peak of an adolescence heat. Usually, punks who let themselves out of control would eventually destroy their lives. But Mitsuru was different. The feeling still lingers around his heart. When they have a sleepover at each other's house, he secretly caresses his hair and kisses his forehead. Mitsuru doesn't know why he is doing this; He doesn't even know what Izumi feels towards him. It is only natural for him to put a facade up. Despite all of that, how he wished he would open more. And if he would open more, do Izumi still deserve Mitsuru after all the things he has done? Or do they share mutual feelings rather?

He only shows interest in the mangas he read. Then Mitsuru realized he was bisexual, not gay. When he was goofing around, Izumi's body puffed, and it became almost the same as his. He was astonished since Izumi was cute and petite back then. Now, he has become a hot, boyfriend material. He was aroused the first time he paid attention to his body. One day, they decided to have a sleepover at Mitsuru's house. They chose to sleep topless since it was hot in his room. Mitsuru had a nosebleed when he saw the naked top of Haruki and especially Izumi. The two panicked and quickly went to look for a tissue. After the bleeding stopped, he excused himself to the bathroom.

He started to shower to cool his head off, but his dick was still hard as a rock. It looks like it is ready to burst. He started stroking himself with slow pacing and gradually going faster. He can't get enough with Izumi he has today. He wants to gobble him up badly. These thoughts ran into his mind while he was jerking. He let a big load off his body and began to wash it. He finished having a shower, and the two didn't suspect him. Even though it was winter, his heater went up too much, and it felt like summer. He used that alibi to avoid any suspicions. Afterward, they went to sleep.

While they are at the hotel, he sneakily caresses Izumi's hair and kisses him on the forehead. It was fun not until Haruki woke up. He immediately went back to his futon to avoid being caught. Haruki can't sleep and go outside. He also saw Yuuji coming back from the bathroom, and he thought he would use him as an alibi if he got caught. Mitsuru searched for Haruki, and he found him on the rooftop. His nightmare became true when Haruki said that someone was "taking advantage" of Izumi and saw someone doing it earlier. He cannot say that it was him.

After he had dreamed about the past, Mitsuru was woken up by Satoshi. "Was the nap good, Mitsuru?" asked Satoshi. "Yeah," he responded. "That reminds me, I want to show you something!" said Satoshi. "What is it this time?!" thought the annoyed Mitsuru. "Follow me to the next room!" said Satoshi with enthusiasm. As he was about to enter the room, he heard a loud sound coming from it. He checked it out and was utterly shocked by what he saw.

"MITSURU! THANK GOODNESS YOU'RE HERE! HELP ME ESCAPE FROM THIS ROOM! I WANT TO SEE IZUMI BADLY!" Mitsuru was speechless when he saw two Satoshis fighting. "Too bad, he went abroad to forget about you!" said the other Satoshi. "What foolishness did you do again, SATORU?!" asked the real Satoshi as he punched his twin. "Just like I said, I used your identity to destroy him and be reunited with Mitsuru!" said Satoru as he kicked Satoshi.

"Stop it!" said Mitsuru as he protected Satoshi, using his bare hands to stop Satoru's punch. "Sorry for dragging you into this mess, Mitsuru-kun. Is it true? That Satoru used my identity to destroy my relationship with him," asked Satoshi. Mitsuru then wailed and hugged Satoshi. "It's true right?" asked Satoshi as his voice trembled. "I'M SO SORRY, SATOSHI! YOU WERE SUPPOSED TO BE ACCEPTED BY IZUMI'S PARENTS, BUT WE DIDN'T KNOW THAT IT WAS YOUR TWIN WHO WAS WITH US THAT TIME!" said Mitsuru. Satoshi was deeply hurt and wailed.

"My dear Mitsuru. Did you ever wonder why "Satoshi" didn't recognize you during your freshmen days? It was because he is the real Satoshi. The Satoshi you hurt way back in middle school, was me! SATORU!" said Satoru as he punches Satoshi. "Stop! Don't hurt Satoshi further, or else, I will not be your boyfriend," Satoru flinched and immediately stopped hitting Satoshi. "Well, well, that's good to hear. Now, shall we leave this trash here?" said Satoru as he laughed maniacally. "I'm so sorry, Satoshi. I cannot help you. We both love Izumi, I am doing this for his sake," whispered Mitsuru as tears fell from his eyes. After the two left the room, Satoshi was left there, caged.

"So, this is how you want to play, Satoru?! An eye for an eye, a tooth for a tooth! I'll get my revenge on you and be reunited with Izumi!" thought the furious Satoshi.
