It’s interesting. If we talk strictly about Princess Agents promo, I don’t see any chemistry between the two characters yet (Li Ying and Geng Xin), but offscreen and off character, they are so adorable together, like in this game promo. It doesn’t help that Lin Geng Xin’s character doesn’t show his emotions as visibly compared to Shawn’s character.
Check out the BTS videos for their chemistry. Heh.
