I think this is the first drama I've watched where I hated the Male lead and was actually fine if they didn't end up together with FL. After a while I just started forwarding the parts with the ML so that I could just get done with the show. I found myself enjoying Peter's parts even more, even though I didn't see him ending up together with Alice, and that was fine. I think I just started disliking him from the start when he mistook Alice for his twin sister and kept bullying her, and all the time he had that stupid confident look on his face, and even when he found out he was mistaken, he didn't seem remorseful at all.
Another issue with ML, after they had reconnected after 13 years, he was always grabbing her hand and at some point it just became annoying, and he acted like nothing had happened and kept forcing himself onto her. And when her memory was reset back to 17, he suddenly had an issue with her grabbing his hands, yet he had been doing it all along. He also started gatekeeping her from Peter when she lost her memory, the only friend she had for the 13 years they weren't in contact, I found that quite infuriating and just stupid. And to top it all off, him and her friends were still making her apologise for the misunderstanding they had had in highschool when she lost her memory, even without knowing the full story, and all the time the ML had that look on his face of confidence.
If i had only found the ML likeable, it could have probably been a better show for me, otherwise the story was not bad. Maybe someone else might enjoy it.
