Girls' Generation member and actor Yoona appeared as the first guest on the YouTube channel 'Kim Young-ok' on the 19th, in an episode titled 'The Real Grandchild Appears: Sa-rang and Grandma Meet Again.' Yoona and veteran actor Kim Young-ok, who formed a bond playing grandmother and granddaughter in the JTBC drama 'King the Land,' displayed extraordinary affection in real life as well. Kim Young-ok, who had wanted Yoona to appear since episode 1, personally bought drinks and expressed her joy, saying 'I wanted to see you the most,' then presented stylish clothing showcasing her fashionista side. Yoona demonstrated thoughtful care by gifting a set of dishes with heart illustrations that recalled her drama character 'Cheon Sa-rang.' Kim Young-ok was particularly impressed by the premium matsutake mushrooms Yoona prepared, saying 'Real matsutake that are hard to find—truly beautiful ones,' to which Yoona humbly replied, 'After that, it became hard to find matsutake.' Their friendship transcended the drama, revealing genuine affection in reality.
