Hello! Anyone can recommend any plot whereby the ML
1) being a jerk / treated a MC like a toy but fell in love only for MC to break up and ML regretted his actions
Or
2) played with the MC feeling out of revenge but regretted it
Any of these!! I just really love angsty stories with ML regretting their actions and felt deep fear of MC leaving them.
Thank you!!
I've read some like "The Third Ending" (chef kisses ) and "Hina wa mitsuiro no koi ni torawareru"
