Transit Love 4 Min-kyung is actually impossible to understand... FR what's her deal

No but seriously, the reason they broke up was because Yu-sik just stopped liking her—it was a classic case of guy's burnout. So why did she come on Transit Love and keep expecting something? It's not like she's unpopular; she just clearly had massive lingering feelings from the start. Did she fall for it when Hyun-ji lied back in Seoul saying Yu-sik seemed to have a lot of feelings left? Even then, you can tell by his actions. Is she getting shaken because he's acting like his heart isn't 100% closed to a reunion? I mean, if she thought about it for even a second... him ignoring her or not responding whenever she brought up marriage, even when she was just talking about 'sometime in the future' and not 'right now'... and not wearing the couple ring... those are all things guys do when they don't like a girl. He said he hated couple rings but wore one with Hyun-ji on the show—shouldn't she realize he just doesn't like her by now? I'm not hating, I just genuinely don't get it. It's not something to bash her for. Min-kyung is frustrating because she only hears what she wants to hear, but Yu-sik is also frustrating because he's so avoidant. If it were me, I'd feel so miserable that I'd just back out and tell him and Hyun-ji to go live happily ever after while I talk smack about them.
