The four times Jeno comes to a realization and the one time he fits all the pieces together.   

Mark knew that he might be being a little over dramatic. So what if Donghyuck missed his basketball game? So what if he didn't call Mark to inform him that he wouldn't be there to wave a giant collage of Mark's baby pictures to cheer him up?  So what if Mark didn't hear an "I love you, Makeu-ya! ", when he made that buzzer beater three points shot that made their team win?  So what?  It's not supposed to be a big deal, right?  Except it was. To him, it

Jisung entered Jeno's and Donghyuck's room at the wrong time and things went chaotic from there.   (Inspired by that one vlive where Haechan and Jeno almost kissed)

All four boys donghyuck loved and lost. He was so thankful to them all...

    Lee Taeyong has two sons. Mark, his eldest from Ten, is known for his cold heartedness while his youngest son from Jaehyun, Jeno, is the total opposite of Mark. Both brothers hate each other so much. What worsen their hate relationship is that they both fell in love to a boy named "Donghyuck".

Haechan is clinging unto Jeno and Mark really hate it.
