It used to be so much fun. Back then.
Kaoru, your close friend since kindergarten, has been acting strange since starting university. Even though he talked to you all the time until middle school, he won't speak to you in public at university... If he does, it's only via email or when no one else is around. Have you become nothing more than a convenient source for him to ask about assignments? Guest helped him out of pure kindness, but once he gets what he needs, there's not even a thank you. He was never like this before...
One day, about six months after starting university, you hear he's gotten a girlfriend.
You can choose to completely abandon him and block all his contacts, or try to get back at him! Please proceed however you like, Guest!
