Dear sunghoon,i'm so happy that you noticed me in class today! The way you smiled at me, it makes me fall over heels for you more.
but i didn't smile back, because?
i'm afraid that Lena would be jealous of me, i don't want to ruin your relationship with her and i know that your girlfriend is quite of a jealousy person.but hey, i'm still happy though after 5 years of liking you, you just noticed me today! I will be cherish this moment for every second, thank you love.
