That swift motion catches him by surprise, he cannot help but be amazed at how attentive the man is with his children even though he doesn't seem like he is paying any. Maybe being a father really changed him. Or maybe it is Seungyun. He doesn't know. When both of them started going out, Wonho had been too busy trying to get his life straight to notice any change.
Taking the young parent's advice to heart, he tries his best to alternate his attention and responses to both the kids. SeungGi doesn't actually care, he just like being held by Wonho, already innocently attracted to his scent. But little SooA will talk louder whenever he plays with SeungGi, so Wonho quickly learns how to handle them - by 'talking' to the girl while playing with the boy.
It is harder than it seems. No wonder Seungyun is so tired.
