I feel like if I was younger I could more easily buy into the teacher-student romance stories, but now that I'm a bit older, I can't see it as anything other than manipulative and abusive. He's cute and young and it's a fake story, but I can't disconnect from all the gross signals I'm getting.

Shes stated multiple times how he acts differently around her. The art style shows this as well. His teacher persona looks very different from his cute everyday look. And the way he treats her is also overly friendly, but he rejects her and distances himself, and then goes back to being close to her.

Thoughts while reading:

Tsubomi wtf are doing dropping into someones house like that? An ex of a teacher dropping by a teenagers house before traveling. Shes kinda trying to set them up in a way. Guuurl no.

Asking couples to hold hands? What is this weird aquarium? Even if its for a couple competition it isn't necessary at all lol.

Reading between the lines his explanation is basically “you make me behave differently and I can’t control myself when I’m with you”. Psht fuck boi

Togyu Minagawa, harassment isn't cute. It isn't persistence. She obviously likes someone else and isn't in the mood.
Also he basically implied ppl who wear eyelash extentions are fake. Get away get away!

Mr. Shishio blushing at her in tank top and shorts. Will this be my last volume? No cause I got another from the library and I feel bad not reading it before returning (I've already done that way too many times). But next time, mark my words, I'm done with this series!
