ughhh I'm about to go to sleep but I just finished reading something that fits. Here's a link: http://www.mangago.zone/read-manga/in_the_cage/
Also check out the novel Bai Lu Qin Jun if you're up for the tears. It's cheating in a way? Even though the seme didn't know he was cheating.
BTW I've reread this manga at least three times and it never fails to stir something up in me.
Omg i'm so happy someone replied to this. Thank you so much for your recommendation. Have a good night's sleep :))
I have read it. But thank you so much ;)
Any manga/novel recommendations where the uke was cheated by the seme? Something like the novel 'the decades of love' or the story of prince charles and princess diana. I'd prefer it to be a BL story. Thank you :>
