Unlike most reviews here, I would say that the second last and last episodes aren't at all traumatic/bad as people are making it out to be. Yes, the second last episode has a bit of angst but which drama doesn't have a bit of angst/plot twist in the second-last episode? It's just like any other dramas with a good/happy ending. Is the drama emotional? Well... Somewhat but not too much.. atleast not for me. Spoiler ahead-
In the second last episode, Day breaks up with Mhok but that was totally justified imo. It was sad but understandable. Day didn't want Mohk to pity him and compromise with his career for his sake. Even though it seems a bit cruel of Day, he did take the right decision. As we can see in the final episode, when the meet and discuss the break up after 3 years, they both realise that it was the best for them. There was no hard feelings involved. By the end, they end up together and Day also gets back his eye-sight and it's a happily ever after. Idk what more people want. It's already good enough as it is!
