The moment when Wooyoung and San's real oppa moment exploded with excitement

I was watching Isabae's YouTube channel today and Wooyoung and San were so funny and exciting.
When Patricia said she was seeing her boyfriend, my heart almost burst when I saw her acting like a real little sister.
Both of you are playful but also genuine in your reactions, which makes me smile all the time.
I find myself watching this video over and over again because of the chemistry between them, and it warms my heart so much.
