Heechul was asked in the episode, “What is the most memorable wedding you’ve been to?” Heechul shared that he went to Jisoo’s sister’s wedding. However, Heechul didn’t know that the bride was Jisoo’s sister. Not only that, but Heechul had never seen Jisoo’s sister before the wedding!

I went to BLACKPINK Jisoo’s sister’s wedding. The funny thing is I didn’t know Jisoo, and I have never seen her sister either. Even at the wedding I just saw her from a distance

Heechul was then asked how he got invited to the wedding, and he shared that he went because he’s known Jisoo’s father for a long time!

I’ve been close to Jisoo’s dad for a long time.

When asked how they are close, he laughingly gave a simple answer.

Why? I can’t have a relationship with him (Jisoo’s father)? That’s the most memorable (wedding) from several years ago.
