After her initiative kissing, both Sungjae and Sooyoung are awkward to each other.
Sungjae is too shaken over her frank answer, yet he knows he loves it.
Meanwhile Sooyoung decides to open her heart to this one man who always stays with her.
She knows she cannot guarantee him the word 'forever' in their relationship, but she still wants to give it a try.
She might think her life is not as normal as others because of her illness, but for Sungjae, he wants to convince his girl that illness cannot limit her happiness, and her willing to live to the fullest.
He wants to always be there for her, and vice versa.
And once they arrive in Sooyoung's place,
"Send my regard to your mom, Sooyoung-ah,"
He tells her.
"Eoh? You don't want to meet her first?"
She asks him.
"I, I,"
"What happens to you, oppa?"
She teases him.
"N-nothing, I think I need time,"
"For what?"
"To re-think about what has happened earlier,"
"Aha! Mwoya! Are you that dumbstruck with my kiss, huh?"
"Ssst!! Don't say that word loudly!"
He puts his finger over her lips, feeling shy because of the sudden mention of their first kiss.
"YA! If I knew you would react exaggeratedly like this, I shouldn't have kissed you in the first place,"
She suddenly regrets her decision before.
Sungjae is taken aback once again with her mood swing.
"No, Sooyoung-ah. I don't mean like that,"
"Fine, that would be my first and last kiss to you,"
She threatens him.
He is bewildered over her words.
"I, I, Oh God, how should I explain this to you, huh? I am too overwhelmed with your answer, so that I am being like this. I am sorry,"
He lowers his voice.
"Pabo!"
She exclaims.
"You do know that I don't have much time, right, oppa? That is why I don't want to waste time when I am with you. I was also taken aback with your sudden confession, but I decided not to save my answer at any later,"
He listens to her earnestly.
"I don't even know whether I can meet you tomorrow or not. My remaining time, I don't know until when it will be,"
She seems to be down in the dumps.
"Every second with you, mom, and Yeri matters to me,"
All of sudden, he hugs her wholeheartedly.
"Uri aegi, how I wish I can share that burden with you. I am sorry for taking your honesty for granted. I should be the mature one here, not you. I should be the one who protects you, and look at this pitiful man. He is once again making you sad,"
He blames himself.
She shakes her head, while still hugging him tight.
"You know it all feels surreal to me. Who would have thought that Yook Sungjae loving someone like me, huh? I have never imagined that any man would love me, but you. You suddenly appear in my life, and then things progressed too fast, so it's hard to me catching up with everything."
