It's in a school setting, guy spends eating in certain spot with his guy friend. Then, the guy noticed that there was someone, a boy, stalking/watching the two (this is vague but I think he thought this particular person was looking or aiming at his friend). When the friend was gone for some time (or day?), he made this person come out or he approached to ask about why he was watching them and asked if he liked his friend. The boy said yes. So the guy like made the boy eat with them so the boy could spend some time with the boy's "crush." But, it turns out, the boy actually likes the guy not the friend.

It might be more vague than the previous one, since it's been a while when I read it. (^～^;)ゞ
