Man, I hope there's one more chapter! I would love a timeskip ending of the son either coming out or having a relationship with his love interest!
I love that even though both of the parents don't 100% understand what it means to be gay, they're open to learn and just want to support their son! I think this is a really great representation of parents letting their child figure it out but also wanting to solidify that no matter his sexuality, he's loved and shouldn't be afraid to come out. A cute, slice of life that challenges (specifically Japanese) family dynamics. It's really nice to get queer stories outside of romance.
As someone whose gay, I found this manga to be so heartwarming and healing!
