you had a massive crush on sunoo, Seoul University's heartthrob. of course, you hadn't confessed. as usual, you're a very quiet and kind student, with good grades

since sunoo was very popular with girls, he of course hasn't noticed you much, so there's not a lot of hope for you guys.

since he wasn't noticing you, you decided to take the risk and started to change yourself so he'd notice, you started off by coloring your hair.

next day at school, he finally starts to notice you more; guess changing yourself works after all
