Gotta admit I’m rather confused because it seems pretty weird for this author to do a swinging/ntr manga considering his two most popular, but at the same time that does definitely seem to be the topic of the manga. Maybe he always wanted to do it and couldn’t get into a magazine or get an editor that was cool with it?
Edit: Also no drama tag yet, which while it is super early does kinda surprise me since the tags are often just taken from JP websites, so I’ve got 0 clue where tf this is going lol
