Wanna hear a real unpopular opinion?

I don't think Min Ho is the endgame.

Jenny Han has a consistent pattern of creating second leads that we all fall for, but they never end up with the main character in the end. Just look at Jeremiah in TSITP or John Ambrose in TATBILB. They were sweet and lovable, and often felt like the perfect match for the protagonist at the time, but they were never the final choice. Min Ho fits right into that "second lead" role — he’s charming, funny, and clearly has feelings for Kitty, but Jenny’s track record tells me that he’s probably not going to be her forever person.

If we follow the pattern, these second leads often come in during a time when the protagonist is unsure of their feelings or struggling with their main love interest. Jeremiah helped Belly realize things about herself and her relationships, but in the end, she went back to Conrad. John Ambrose was everything Lara Jean thought she wanted, but she couldn’t ignore her stronger connection to Peter. I think Min Ho is likely playing the same role for Kitty—he’s helping her see a different side of love, but her story is probably going to lead her back to someone else, based on how Jenny Han tends to wrap things up.

That’s just my perspective, maybe the pattern won't be followed, but just looking at it more objectively.
