Wrong locker love letter

Hi! asking for help.

It's about an uke who got erotic letters from a popular student but turns out it was the wrong locker. He caught the seme by staying on top of the locker. Behaves like a cat and the seme was wearing glasses. There's this chapter where the seme broke his glasses and the uke helped him buy food at the canteen. Seme remembered him through his warm hands.

Please help! I've been looking for this for awhile. Wanted to reread it.
