There's only like 3 or 4 new chapters. Okay, so what happened at the end of last season was that Jaehyun confessed to MC and she accepted. The new season starts MC and Jaehyun established as dating, they buy matching shoes, and do couple stuff. The bus driver turns out to be regressed back in time too and he questions whether or not they were willing to go back in time if there was a way. Eunjae says "i'll think about it" and MC is like "For now, no." And when Eunjae asks why she said "for now" it's bc MC starts to have dreams about Jaehyun again. There also is another plot point where Eunjae confessed to his past first love, but she rejects him.
So the debate for ML is still on-going.
