Really? Do you have a link to the raws? They're only on vol 2 here
The MC told his mom that he has a boyfriend but his mom wasn't shocked at all and even wishes him good luck. So he asked his mom why she wasn't mad at him for being gay and his mom said, why would she be mad at him and his boyfriend. His boyfriend is doing her a favor for loving her son.
