This isn't a drama which I would normally start but my sister wanted to watch it. She dropped it two episodes in btw, but because I suffer from never drop disease, I put it on 2x speed as I was determined to finish after it was rotting in my On Hold list for over a year.

I'm not saying that it was a bad drama but it just wasn't for me. The whole teacher-student relationship was weird especially since the FL was just 16-17 year-old while having such a big crush on the teacher, who was 10 years her elder. She was very clingy towards him, even gifting him a shirt on his birthday and when the two of them got trapped together in school overnight, she pretended to not have her phone just so she could stay with him. Welp, at least the teacher wanted to set her up with his younger self. That was basically the plot of the first five episodes, after that it got a bit better since the ML got back to present and his younger self traveled with him too.

Then it got more interesting, I liked how the ML at the end had so many different memories of the past because it was like he lived all of them, but each was different a bit when it came to the terms where he and the FL met. However, I would prefer for the time-travel to be explained a little bit more.

Overall a 7/10 rating, not really memorable and there were some things bugging me.
