basically
> mc grows up thinking he's the cutest thing ever, because his parents and the ml would always say that to him
> when he gets into highschool people start talking how freaking plain he is and that he's average and nothing special
> he doesn't give a fuck until he hears the ml (who is his senior) agreeing to what his friend said about him (that mc is average and not cute)
> as a senior in his last year ml basically has his own life preparing for university entrance exams etc etc and he doesn't pay attention to the mc
> mc starts falling into a real problematic case of low selfesteem because he doesn't see himself as cute anymore and just your average ugly highschooler
> mc loves ml, but he thinks ml loves his another friend (aoi), and both of them are ikemen so mc thinks its better to not bother the "perfect couple"
hope that it made it easier for you to understand something (i know it didnt because this story is messy asf and full of plot holes as of now)
