Mother

that mother surely is not mothering.

Abandoned his family, put his son into a mental institute with an specific order not to treat him properly...

I'm surprised the MC & ML aren't that angry with her, that woman deserves a public humiliation at the very least and a complete restraining order with the MC.

the ML's a lil bit annoying too, his pride lead the uke to harm himself, if he just say 'I love you' and explain the situation honestly in the first place, the uke wouldn't have to suffer that much.
