What about biological mom????

prolly dead after child birth

And this dude forget about her in just a few month :))) nope this is a turn off for me

Political marriage maybe

I think someone said that the little girl was adopted

I hope she was adopted.

The child should be at least 1 year old.
Does it say her age anywhere?
(=・ω・=)

Him forgetting his wife whom he was most likely in a political marriage with after one month isn't a turn off for me. It's his actions that deliberately treat others (such as the FL) like trash beneath his feet that turns me off.
