She noticed him and boy get embarrassed because he was starring at her and stared walking again 

But the girl again started staring at the lake but the the colour is changing to red now. 

He finally get into home. he goes to his room and lay down on the bed and started thinking about her why is she staring at the lake and why the colour of her is red. Usually he saw people with red colour if they are really in depression and very sad 

Almost Every time he saw that colour they are mostly 20-24+ .

And only sometimes before and in the last month of the year 18 or 18+

But never anyone young as her. 

But He don't go outside that much only for school and if any important.

He falls asleep while thinking...

His grandma was going to the kitchen and saw him sleeping. But she didn't wake him up. 

The sun is almost down and it's getting dark now 

Suddenly his mom is calling him. He woke by that and go to his mom. 

His told him to go and get something ingredients that she needs to make dinner. 

His mother says why are you still in school uniform, change it and then go to shop 

He said he will change later and he go outside, close the door and started walking. 

When he was going he saw Nishi, still there sitting on a bench that was close to water. He was surprised that she is still here and he is more surprised because the colour is kinda purple and it's more dangerous then red. 

He think that he have to help her. First he goes to the shop and buy the things that his mother asked for and also buy 2 drink and a burger.

That burger was shops own original burger. 

He get out of the store 

He took a deep breath and go to Nishi and set on the side. 

And ask why she is still here and it's dark now.
