The more I think about this season, the more I like it. I watched the movie version of the 1st season, and that was fine, but didn't seem to go too in-depth on the characters, whereas the second season was the opposite.

The show started with the core of it, in a later revealed flashforward: Seo Joon saying "you need to express yourself more" and Ji Woon saying "I love you, I love you"

Then the following 10 episodes were just the painful way for how there two got to that point.

I don't know if I would call the show realistic, but I certainly think the characters are consistent and true to themselves.
If we start with Ji Woon as this season was mainly about him; he had been in a long relationship where he hurt someone and was badly hurt in return. This had left him feeling guilty and ashamed of himself, afraid to open up to another relationship. This led him to run away when things got rough, to cruelly push someone he loved away, not just to protect himself, but also to protect Seo Joon in the long run "he is better off without me".

Seo Joon on the other hand had gotten his heart broken but clung on because of his issues with abandonment, he tried to withstand the cruelties Ji Woon was doing to him because he could see the other one was hurting, but in the end he realised that he had to give up, had to stand up to himself to do what would be best for him, despite his love.

At the conclusion of their character journeys, Seo Joon gives up on Ji Woon, then forgives him - and Ji Woon who has been able to heal some of his past hurts throughout the show is finally able to express what he feels, and what he wants, leading the characters to build a relationship together that fits the both of them.

After Ji Woon has returned to Seo Joon in Seoul, I really like their apology/forgiveness scene; Ji Woon has let his walls break, is crying and speaking his mind "I am jealous, I don't want you to call or laugh with others" and while obviously that's not healthy, it's not the words he is saying that's important, just that he is expressing them, that marks his growth and shows that their relationship can work.
Then the lovely epilogue moments at the end show how they have adjusted, Ji Woon is vocal about his love, they are commuting back and forth and it feels like they are both now on much more equal footing. The makeout scenes were fun as always too 😄
