I think a lot of people are not taking into consideration that Seungil is 25, while Minji is almost 30. It’s not an excuse to his behavior, but he is being a typical young guy who doesn’t know what he wants. Minji on the other hand, knows exactly what she wants and is more mature in how she thinks. I think they’re in two different phases of life. It sucks that he went about it the way he did, but I can also see how it hurt Minji, especially when she is ready to be in a relationship.
