The substitute relationship
Fall in love with the substitute ( ml is white moonlight to the dude mc is being substitute for)
The world without you
(Also wym “a few chapters” for black lotus bro the mc suffered for at least 70 chapters ╥﹏╥)
Unfortunately already read them
(Sorry completely mixed it up) I mixed it up with that one popular series that's always mentioned when someone brings up substitute bls, but it's also a reincarnation + system story. Sorry for the mixup again I'm bad with names)
May or may not have already read them but thanks nonetheless:)

Hi , need help finding new sad shounen ai series where the MC is someone's replacement, I want more recommendations please.
Nothing like Black lotus since that role only lasted a few chapters, more like the story thats quite literally just called "Substitute". I want to hate the same through and through until he actually tries to win mc back and has a good redemption ark, I want the angst to last longer than the redemption though, I wanna sob
