Nop he could be younger it's said that high school in Japan is 15 till 18 but if a child got early admission it can also be 14 - 17 so he's at least 14. But Natsuki is the child means when he goes to high school they have an age gap around 12 - 13 years probably. I'm still not sure what's the fighting point in the comments but if it's the age it wouldn't be pedophilia if Natsuki chased after Mika it would be gerontophilia
Oh I didn't about that. Lots of "ifs", I guess we'll see.
Yeah well see. I know why I normally stay out of the comment section.
Thank you for reading my thought process without being offended, because it wasn't meant to offend anyone (after I read it again it sounded kinda mean, sorry)
we don't even know whats gonna happen, there's a single picture.
one thing is sure: mika is 16 at least, that means legally(in japan and a vast majority of countries) there's no pedo content here (but we'll see maybe there is in flashbacks)
about grooming : you go to daycare until you're 3, after that Natsuki is not supposed to see Mika, also your first memories are mainly from when you were about 3/4. But I'm guessing they kept contact in some way, but was it a grooming appropriate closeness ... we'll see.
Also Mika is not really a daycare worker, he's a high schooler who's helping (at least that's why he mentions his aunt) so they are less than 20 years appart. Sociologists said, for a relation to be socially accepted, the younger partner needs to have at least half the age of the older plus seven years, we are definitely not getting that so reactions in the comment section are normal but laws don't use that rule and there's no crime.
