The next day Ren and Rosie went the university together as always.

On the way, Rosie asked- “Ren, isn’t professor Ken coming with you?”

“No, Rosie. Big brother is the chemistry professor. And the professors go to the university an hour before the students.”

“Oh! So that’s why he isn’t with you!”

After going to university they found out that Ken will take their chemistry class.

Ren and Rosie had the same schedule so they were together every classes and in the off periods too. They used to spend the off periods in the canteen or in the library or in the sports section. And sometimes when they run into Ken, Ren used to cling to him and Rosie always greeted him respectfully. Ken noticed that Ren and Rosie were always together at home also at the university. Just when Rosie worked in the convenience store he used to alone.
