I watched this before the OG "On Your Wedding Day". I was impressed by this storyline than the OG because of few reasons:
1. The athlete dream gone cause of injury sounded more lie a logical reasoning for the ML to say that he regrets it
2. The starting school portion between the two was more genuine in 'My Love' in my opinion.
3. I cried at the end for 'My Love' but didnt for the OG (maybe bcs I watched it back to back)
4.The ring portion and the last minute to wedding hall portion also felt like better written in 'My Love' than OG.
I would recommend watching this if you like watching Chinese drama more than Korean Drama as a foreigner.
