"HYUNG, I understand where your fear is coming from. But, to be honest, I'm not worried about that."
"You're not?" Sohee asked, lifting his head to look at Kim Heedo's eyes. "What do you mean by that? I know that you love me and all. But childbirth can have a bad impact on my mental health, you know? That's why postpartum depression is a thing."
"Yes, Hyung. I'm not taking your worries lightly," Kim Heedo said carefully while gently rubbing Sohee's back. "Of course, if ever you get postpartum depression, I'll take care of you. I'll stay with you as we seek professional help to help you get better. As much as I love our babies, I can't promise I can love them as much as I love you, Hyung."
"Yah."
"I'm just being honest, Hyung. Of course, I'll take care of our babies. But if you get sick, I'll pay more attention to you."
"That's a motivation for me not to get sick, then."
Because Sohee could tell that Kim Heedo was serious.
