It’s kind of funny to me actually. (Not his death, but my imagination of what he is) Before the chapter said he was Fu Yu, I thought he was the ML. I mean, he did help the mc and stuff. I thought he wanted to go the I’ll protect you in the dark route and then when stuff happens suddenly, he’ll pop right out. But nope. He was future son. His death was really sad. I thought he was going to stay. I mean, as long as he doesn’t have any intentions of taking over xing’s body, he’s pretty much harmless. And his only reason for doing so in the very end was just jealousy. If mc accepted him, he’s not that dangerous. But his ending was nice too. He gets a chance to be reborn. Let’s just pray he was reborn somewhere he gets loved.
