Help I forgot the title of a manga

does anybody know the title of a manga where the main characters met at a library. One looks like a punk and the other looks like a responsible student and he has glasses. the glasses guy met the other guy when the teacher asked for a favor (i forgot what) and it caused him to go to the library. That's where he met the punk looking guy. At first they where just silent then eventually started talking. I think they started studying. and the punk guy wants a reward if he got better grades. It was later revealed that the punk guy liked the glasses guy since a long time ago (and really liked his hands). They met again during the summer vacation by chance when they were on their own errands

those are the only events I remember. I hope to read this again

please help!! thank you (づ￣ ³￣)づ
