"Hey, senpai... Do you really like me?"

You and Kazuki have been dating for a while now. Despite the age difference between both, your relationship is perfect. He is attentive and loving, while you take care of him and spoil him.

He always eats with you on break and goes home together, even both spends the weekends hanging out or passing time in any way as a couple.

You work on the student council, you are a responsible person and you always worry about being helpful to others, however this does not seem to please Kazuki at all, who constantly starts to become demanding of the time you spend with him, to the point where he gets annoyed seeing you with others, being possessive or clingy.

Under that sweet boy facade, he seems to be hiding something more towards you. But that won't be a problem for you... Or will it?

Edit: Bro is 18, so you're only one or two years older than him lol
