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.
