I re-watched S1 before watching S2, just to see if my original rating (7,5) would stand. It did. I liked the cuteness and sweet interactions. I was expecting something similar for S2 (I try to avoid spoilers as much as I can). But I was in for a surprise. The bittersweet heartache starts in the first minute and hardly lets up until the forelast episode. Where I loved Ji Woo and loathed Seo Joon's railroading him in S1, it was the reversed in S2. Ji Woo is being a closed up a**hole and Seo Joon is trying with all his might to save their relationship and show his love. His honesty and candor are heartmelting and I could not understand how Ji Woo could resist. The slow meltingf of the ice wall Ji Woo has around his heart is shown with great subtlety and the hardening of Seo Joons heart made very clear. In the end I could not see how they would ever get back together and feared for a BL-style weird plot-twist, but I'm happy to say that the way they ultimately find each other is so raw and emotional, it simultaneously broke and healed my heart. I loved it.
