I'm happy for Hye Yeon, she saw something in him and made this all happen when everyone was all ??? And she was so excited at the shoot. The photoshoot was filmed for the latest episode of I Live Alone, and the reactions were so much fun! Starts at around minute 47. Tagging webtoons because that's what he does lol.
