Ok, so a cool guy is walking down the hallway with his friend, and notices a quiet guy watching his friend. So he offers to help the quiet guy, and tells the quiet guy stuff about his friend. They end up becoming friends, and the cool guy likes the quiet guy.

It's similar to Renai Kyoutei Nukegake Nashi!

Please help!
