PREACH!!
the only time that trope is good is when the one receiving those words literally points out that it's such a cliche and laughs or calls the other person out on their jealousy
I think it's partly a cultural difference... (considering where it's written, y'know). Somethings are exaggerated, but somethings are also half-truths.
The reality is, "social image" is a big deal in many Asian countries... and self-esteem is a bit more social-relationship-dependant...than it is say in north america.
For example, students in Japanese classrooms rarely raise their hands up because they fear giving the wrong answer or looking stupid. Things like a whole class laughing at you for your mistakes is also very real. (just to give an example)

I agree with Ruri it's definitely a cultural thing although i do agree this trope should die
Why do characters always wanna tell the main couple that they're not "good" for eachother or whatever just because one of them is popular. I get that if it was a friend or someone close to the couple and they saw that it was really toxic or something then yeah. But most of them are just jealous and selfish and as a plot device I'm tired of it, like it's an overused trope. Mangas, especially shoujo manga makes it a main point to focus on cheesy overused tropes for laughs and shit but it's honestly tiring as a reader to read 10 mangas and they all be the same.
