Relationship goals??
Sian's pick did not surprise me at all but the reason she picked him did. I don't know if this would be the correct translation since all subs are different but she mentioned that being with Junseo made her feel tense, uncomfortable, and horrible (don't come at me for this please, that's just me translating directly what the subs in my language were) and that's how she knew she liked him because that's what love/a crush should feel like rather than feeling at ease like she did with Jeongsu.
I cared for neither ship so it's not like I'm saying this to claim she would've been a better match with Jeongsu, but the idea that you should feel uncomfortable around the person you like is wild to me. Everyone's experiences and opinions differ and her opinion is of course valid, but it did shock me a bit to hear her say that. Again maybe my country just has incorrect or overexaggerated subs but I do hope viewers and especially young viewers realise this is her view (and it's fine she has that) but it can also be a dangerous one. Obviously Junseo is not a dangerous man but having such views with the wrong person can be dangerous and bad.
