I Thot You Was a Toad's manga / #Sakumoto Ayu(2)

Romances involving three sets of dorm-mates at a boys' school.

Boy with a hand fetish and an interest in jewellery-making, specifically rings, meets misanthrope whose dislike of people has to do with having been so frequently harassed for having a beautiful face. Misanthrope doesn't know what to do about somebody whose only interest is in his hands, but at some point in the story, he does want that interest to expand to other bits of him.
