Vol 5: Ch 363 - They are really too smart
After the Jang Twins apologizing to their cousin, the awkward situation a while ago suddenly gone as if it didn't happen to them.
Ken : (Suddenly remembered something) ah, that's right Sis Raq?
Raq: Y----yes? (Got scared because her lovable cousin suddenly calling her with affection now different from a while ago even though he calls the same one but there's no feeling of it when he called that time)
Ken: Eh, why are you so scared, Sis Raq?
Raq: Not scared but just caught off guard because you suddenly call me with a feeling this time.
Ken: Ahh, that's right, and sorry for that Sis Raq. (Then whisper to his Younger Brother) I'm tone deaf so you do it.
Ren: And how did you know of what I'm thinking about?
Ken: Well you're my twin brother after all. Ahh, Sis Raq, Ren has a surprise for you.
