Okay I had saw an ad about this, so the manga is licensed. It's just been awhile and cant freaking remember the name

The wife has been wanting to have sex with her husband but he never is in the mood so she questions it. Then one day she catches him kissing another man. Rather than divorcing him she tries to think of this of a way to build their relationship and I think they become a ploy relationship. And the one the husband is with actually likes the wife, I think.

I'm not sure but I think the wife see's the kiss through the door hole but I think I'm just think if a different series here but I'm not sure

I haven't read it, but I've been seeing it around -- is it Me, My Husband, and My Husband's Boyfriend?

YESS THATS IT!!! Thank you so much
