I Thot You Was a Toad's manga / #Aoyama Toomi(2)

Aoyama Toomi took on some very trigger-laden subject matter, especially in the first story, but she treated her characters with such respect and kindness that it overcomes the power imbalances. The stories are generally light with realistic emotional responses. The main story is about a doting uncle and his relationship with his introverted teenaged nephew, based on an emotional connection built up slowly over time and games of chess. There are two secondary stories, one about mistaken identities and judging people on appearances, and the third about how cats respond to gentleness.

An investigative reporter tracks down an elusive and mysterious scientist/mathematician, insinuates himself into their lives, and it doesn't even phase him that this doctor and his sidekick have horns on their heads.
