This manhwa's ending feels like a cop out. It's like the author wanted to please the fans after they broke their relationship apart on Chapter 99 and ends it in the most rushed and cliche way possible. The fact that we don't get much POV from Tae Woong really makes their reunion feel unearned. And the huge timeskip is so unrealistic, like 6 FUCKING YEARS!? It just doesn't sit right with me at all. I think the author fucked up with how he handled their relationship and just makes the most generic way to bring them back together.
With that being said, it's still a great read even though there's a bunch of parts that are too dragged out / too frustrating, badly handled miscommunications for the sake of drama, and awkward plot devices to transition to another arc. But the ending in particular is so unsatisfying and doesn't mesh well with how the rest of the manhwa is structured. Basically a shoddy attempt of a happy ending.
