Way late to this but yes shio is a kid but i would recommend looking past that as this manga has so much more and is something i’d recommend reading. It is NOT an alternative to killing stalking as they are a loving pair who love each other a lot. I wouldn’t call it grooming since shio was the one who reached out to sato and did it all consensually, she also did NOT get kidnapped. And it includes romance aspects. I don’t know why the other reply would lie to you.
The manga has grooming and other toxic traits, I never said it didn’t. My comment was based off the definition of grooming (which by definition involves some sort of manipulation/abuse and predatory intent) and only about the two main characters, & as I’ve stated Shio was the one who approached Sato and did everything willingly, which is the meaning of consent, in case you’re not aware. I don’t know what you’re picturing or imagining but if you haven’t read it do not try to accuse me of doing things I never did.
They're both minors full of issues and troubles, and the most they did was give a peck on the lips which was initiated by the youngest. Yes I'm sick in the head ooo sue me for actually being able to tell apart between grooming and two struggling people. Just because the term grooming exists it does not mean it's applicable in every situation.

Someone recommended this as a GL alternate to “killing stalking” so naturally I ran to check it out. Before I start reading - is one of the main characters a literal child? I’m reading the description and it keeps referring to a “little girl”
