I think its super unrealistic because people move on, grow up, and change. Its human nature.
The only good time I've seen this trope happen in a good way is with Seikai Ichi Hatsukoi. The two were in love in high school. One moved away. They meet up again later in life, both grown and changed. And ended up falling in love again, but distinctly with the new person each had become. Soooooo good
no, i see ur point, and def agree. it seems a bit implausible you’d still be love with someone after having gone through big life changes, considering taste change, also as it GENERALLY makes more sense to fall out of love when the other person shows no sign or lack of reciprocation, especially as a reaction of your heart giving up and moving on. this also would’ve been more plausible considering how long the mc and ml were apart.
but also, stories doesn’t have to necessarily be realistic to happen, also considering someone being “stuck” on your first love isn’t entirely impossible. i always thought this troupe was used to bring more chemistry to a pairing, it fills in the space of their time apart with the longing troupe, so when they reunite, it gives more push for the romance. a popular example of this troupe would be ‘heaven’s official blessing’.
theory aside, i think the extent ian puts into pursuing the mc is a matter of how much you vibe with what’s happening. some might find this extensive pining, poetic and romantic, and others, implausible and weird. we all have different taste and i think that’s all there is in terms of discussing the plausibility of this troupe.

I have seen this trope many times in manhuas, but is it really realistic that you would go back to your first crush or something and try to pursue them for love? Even though you changed town or country, you're now older, you have a job, you have a different life, you met many people, but somehow you're still stuck. I can understand staying stuck or idealizing first love, but going to the extent of coming back for that one person or putting your career in stake just sounds weird to me. Or unrealistic, but I really want to hear thoughts on that.
