No actual runaway chasing arc. They decided to live separately but jinhyuk would still be present as the baby's father and responsible as a spouse, it's up to asel whether to accept jinhyuk or never forgive him for life. Jinhyuk's visiting often for the baby but tried not to be in asel's presence as much as possible, they'd only contact each other when necessary. Tho later jinhyuk was noticed by asel watching him from afar whenever he's going back from prep school (for taking college entrance exam). Asel started interacting more with jinhyuk little by little. One time their baby got sick so asel called jinhyuk, jinhyuk stayed with them. Then they slowly rebuilt their relationship.

Somebody give me spoiler on the runaway and chasing arc(〜 ̄△ ̄)〜
