I love this so much, all of the characters are cute and misunderstandings get fixed almost instantly. It's so wholesome and so easy to read that I binged it all at once, you can't help but root for the main character as well as Tsumiki. I have dealt with a lot of similar feelings that Yutaka is dealing with, no sense of self and confusion of who you are. It's something difficult to overcome, but with Tsumiki by his side I think he'll realize there's a ton of things that he enjoys that he didn't realize before. Sometimes it's hard to notice certain things about yourself and you need someone to tell you, or because you're always thinking of others it's hard to think about your own things.
Side note, I can't help but think of possible other couples. Like the human girl whose obsessed with learning about Genjin and the spider girl would be so fucking cute together. I can't help but see something between them, but that could just be my gay lil heart's wishful thinking. Plus the medusa girl and the invisible dude???? They're SO cute omfg. Even all of these characters just as friends have such great compatibilities with each other that they'd all be friends for life, it's such an endearing manga to read that I can't help but want to read it forever.
