MC and ML ending up together is a way happier ending than ML and the OG!fiance. It's explained later in the manga that the OG!fiance was always in love with ML's. In the OG timeline, she died because of a stalker. However, she lived in this timeline thanks to MC. ML speculates that he and OG!fiance got together because of her death. ML sought comfort from OG!F as he was a childhood friend and OG!F gave in because ML looks like a male version of his sister. In this timeline, ML is seemingly disturbed by the idea of him and OG!F dating. This timeline is definitely significantly happier than the first. The OG couple is honestly better off not being together because his sister is ALIVE
Something about this ML is giving me the ick. The way he talked about his extremely happily married friend potentially trying to steal away MC or how he'd be jealous over their hypothetical son saying they'd want to marry MC sends my red flag signs off. I've read yandere ML stories that set off less of my red flag alarms than this man
Just fucking date already
