After ch. 2 I want them to have a child, but they won't?
The content you have read here spreads over 2 books, 3 chapters each. The only part that hasn’t been scanlated are extras. Their kid is not mentioned in the books.
Here is him (his name is Sumire) https://twitter.com/tsuba_daeki/status/1123405742621376513?s=21
I like the red head and I feel sorry for him. Even the straight couple got some progress with their relationship. ┑( ̄Д  ̄)┍
