I felt like the weakest part of this was the overarching story and the side characters; on the other hand, the main leads had a great dynamic together and I especially loved their college days.

The main leads were pretty much the only characters I cared about and I utterly loved their dynamic and them individually. The FL was shy in public but wasn't the typical stupid, ditzy FL — she was open and warm around people she trusted, she was smart, and she knew what she wanted in life and never let her relationships define her. The ML was outgoing and fun, his character development tragic but understandable.

Unfortunately, this drama suffers from the same issue that a lot of short college dramas suffer from — wanting to give side characters a romance arc and yet not dedicating time to their backstories and personalities. FL's best friend was annoyingly peppy; the other roommates and all of ML's friends were the same and I couldn't tell them apart.

The dual timelines were a little hard to tell apart — I'm not sure if this is more of an editing issue where the ambiance of the scenes and the look of the characters weren't different enough.

The overall plot with why the ML had to leave is ultimately really cliche; it's definitely a trope that I've seen before and expected. I felt like the development of the relationship post-time jump could have been done better, but ultimately I still liked how you could see hints of the characters' old personalities as well as their growth during that time.
