Sex with the Love Interest! But I'm an NPC!
When I tried to enjoy the life of a neglected husband, I ended up taking the route of affection!?
I just read the novel and it was pretty good, you end up liking all the characters so yeah don't worry about the "official husband". Overall I'd give this a 7.5 out of 10. Here's why: (spoiler alert) MC only admits he loves ML almost at the end and their relationship feels kinda empty, they don't truly develop much other than sex and cute scenes. The civil war plot was a nice change of pace but it wasn't all that well done since it was a time skip. If their relationship had a deeper connection this would've been a 8.5 out of 10, mostly bc the story isn't all that interesting (characters are shallow and so is the story).
