I don't get FL. ML deserves to know he has a child, he's not a jerk either. He wants to protect ML so ge shines but never really ask for his opinion . He loves her yet she keeps lying and running away and cry that she wishes for him to recognize their son on his own. Even though they look the same, a lot of people look the same in this world so he wouldn't assume it was their son and to top it all off, she lied about his age which is the only way he can confirm. He believes the mother, and it would hurt him if ge expect and find out it's not his son so I get why he didn't pursue the thought. And FL always wants to run away so what could he do. I'm sos frustrated with FL  she's too passive
