It Started With A Love Letter

You're in love with Kai but it seems to you that he doesn't feel the same way towards you. You confessed to him through a love letter that changed everything, you grew tired and sick of loving him because you thought that he doesn't want you and he never paid any single attention to you and worst he let you feel pain and heart ache. Your mind hated him so much but your heart still belongs to him, for three years you tried to forget him and managed to somehow but he suddenly showed up snapping you back to reality that you love him, only him and no one else.
