I think it would be a bit too much for Rourou. I guess he is just to young to understand their explanation and even if he did, Rourou may be an outcast in his class because of being a son of a gay couple. He is a kid, he would probably tell others. Adults are really cruel, those who are homophobic can forbid their kids to play with Rourou. From my own experience I know that having a label put on you in your early years and being pointed at by other parents and their kids, can traumatize for life.
But yes, they should talk with the teachers at least, so that they can help Rourou with those situations.
Feng Feng is obscenely wealthy. If it’s an environment that doesn’t support diversity in family structure, then they have the money to find a school that does. Obviously this isn’t the case for most families, but they are not most families so that should be taken into consideration. However, before they explore other schools, they should let the teachers know. That would make clear what type of support system they are working within for RouRou’s education. I also disagree with not teaching a child from the get go that they have two daddies/two mommies or for the non-binary folks, simply two parents. Of course, the individuals within the family know best! I just have seen both scenarios and find the kids that grow up with normalizing their family structure (whatever that looks like) end up feeling less conflicted about it being different down the road.
Too much pressure YiYi and Feng Feng! Save the world??? He needs a more concrete answer for the onslaught of inquiries rather than thinking everyone is evil that asks about his parents. They should be at least informing the teachers so they can better protect RuRu from his peers’ incessant asking about his parents
