Jung Arin and Kang Younghyun are happy with each other and their 4-year relationship that started during their lasts year of their university life until now that theyre working on their respective fields; however until one day, a certain nightmare would change their lives.(inspired by the song 我很快樂 I'm Happy by Eric Chou) 

Black and white, sun and moon, light and dark. Two different personalities fighting for one dream and love, but is the fight worth fighting for, especially when there are parallel lines between them?   (loosely inspired by yesung's 평행선/parallel lines; also readable in AO3)

Four different men dealing with their very rocky situations, but those things made them bond together, but in a different way and reasons. Would they succeed in this kind of attempt?   (inspired by a song from The Vamps; also readable in AO3 and Wattpad)
