Try "Half of me", same author of Payback. It has an intriguing plot and a healthy couple who develop from distrusting each other to being a cute understanding duo. Their dynamic feels authentic, rather than forced stereotype, because we can see them growing fond of each other throughout their journey. Its slowburn. The manhwa is on hiatus rn because of artist's health but you can check out the novel. I'm actually obsessed with the story to the point I have re read both manhwa and novel multiple times
okay this might not be exactly what you're asking for but trust me- what i recommended is going to give you a good time (how do i word this without sounding like a pervert)
“Shining Summer” and “Monochrome Rumor”
I'm not finished and I don't think I will, this has the same problem as At The End of The Road for me, where everyone hates the og owner of the body and no one cares they tried to kill themselves and tjat just makes me really sad and frustrated. I get more interested in that the actual plot and romance aren't interesting to me.
Anyone has a recommendation like this but they actually do care about the og owner? Or maybe it just follows both of them as they switch bodies? I don't get why they never show us what happens to the other one when they switch it could've been so interesting to see them meet
