Just some forewarning (as you wont get this from the tags): the first couple in this manga aren’t really a love story. The first couple definitely leaves something to be desired at the end as the plot feels unresolved.
Still worth the read for the smut especially if you like bondage, degradation etc. The second couple is a little bit better but not by far. Though at-least it seems like they actually somewhat like/have feelings for each other.
