The first thing I liked in this series was how the process was smooth like butter. Nyhaha the confession was simple, the misunderstanding was not that angsty feeling, and they both feel each other (like sync).

I want to say much about the main characters but, as someone who is always driven by the 2nd character, his suffering was unbearable! I dunno if this was me, paying attention to 2nd character than ML but I think, FL and 2nd character had more memories than the couple hehe. I found it quite unfair for the 2nd character to do all for the FL but the FL always takes it lightly (not that she intentionally did that, I think that's how it works for a person who is in love--I dunno). I'm forever rooting for 2nd character like this!

Many characters change their personality as the story proceeds. Most of them were annoying at first but became better as the eps ran.

The ending? Net says it's a happy ending. For me, it is not. nyhahha that's the bitter side for me. At the last 5 eps, I can't help but feel annoyed by FL. Annoyed to the situation she only thinks one way because that's the only way. In my perspective, this kind of sacrifice shows selfishness instead of being selfless. It's like, she was blinded by that hope that her life would save everyone and started to disregard the pain and bitter taste it left to people who loved her. That's not a better ending for me. People who were left behind will live in an empty void and the last will cannot prevent that (demanding they should live a happy life and such).

But overall, I like the process they had. The characters were awesome in a way they grew for the worse or for the better.
