Into the rose garden?
Camping here I want read something like that too (=・ω・=)
(Spoilers?) Not the mc but he enters mc’s world from a different dimension and figures out mc is his past lover who he killed and they get back together

I don't have any recs sadly but can I please have the links to the examples you gave
Reborn- deceiving my financial backing husband (shounen ai)
Again
They weren't together but old mc was a pretty mean guy and he ended up offing himself and got a second chance at life thanks to his mom giving up her food fortune and she was a shaman.
I personally thought it was so cute and it had me giggling and kicking my feet with the mc and ml's relationship but people disagree cause they don't like the mc
The story's called "Again" btw...I wasn't saying...again...LMAO
Recs of yaoi where one of them regrets mistreating his lover and somehow has a second chance (rebirth, time travel) to make things right after regretting what they did???
Ex. Rebirth or The wife is first
