I am reading the comments, and it's like this:
"What a wholesome relationship yeah wohooo"
"This girl is a $%@&#"
"Yeah, good relationship goals."
"Let her be guys,"
It's the craziest comment section I have seen in some time.
My two cents... look, the child is a small kid, and he likes his noona, so he doesn't really know what is going on (he is 9 I think).
The young woman (because if I remember right, she is in college) could be confused because she is a closeted lesbian or bisexual... but it could also be because her parents were gay and that's why she lives with her grandmother (her family split after something happened), or she could have been influenced to think that the relationship is wrong and so she wants to "save" him. The thing is I understand that she wants to help out of fear.
BUT... she should know her limits as a young adult, and know that no matter what her idea (ideals) may be, she shouldn't share personal information with anyone, especially not your own. She could be passing it to someone who is a scam artist who posts as a blind date company (it's has happened), or she could just spam him with so many calls that the important ones don't get through. The thing is that she should know better, plus there is such a thing as taking things too far. You may have something about a partner but trying to break them up by introducing someone else it's an awful way to do it.
