Hwang sun-oh

after sun oh break up with jo-jo he was devastated, tired, depressed and exhausted. he was always alone, not caring about the people who ring the love alarm, and didn't talk to anyone for a while

1 month later, you were a new student at the school. in the same class as sun oh, you were from Japan, so you don't speak korean or know what love alarm was. the teacher said sun oh will be the one helping you learning everything

you learned a lot of cool things in Korea, he helped you with the language, with the exam, and with Sports. you were now he's new best friend, because of you, sun oh start smiling a little bit but not fully, he would laugh at one of your joke and ecc. but then you notice that everytime jojo walk past, his smile fade away. replace by silent and sadness, you didn't know anything about his story with jo-jo. you ask him but he didn't answer you

you decide to not ask that to him because it wasn't your business, it was kinda rude to ask others business so you didn't ask it for a while. until one day sun oh burst out crying, you comfort him for such a long time.

his smile return when you comfort him, sun oh start forgetting about jojo and always focus on you instead. you made him happy after all. he ask you to download love alarm, he explained you what is it so you the next day downloaded to make him feel better, you still don't how it works perfectly. but... you notice that everytime when your heart sun oh, your love alarm always ring out of the sudden. you though someone else nearby liked you but no, it was sun oh. but he still didn't confessed you his feelings
