After watching them for a while (a few years) I've put two and two together that Lao qin knows he has feelings for her but she herself isn't sure if she likes him in that way.
My heart is so full in this episode 😍 In the show they're all in good terms and loving to one another but there's just something natural and sincere with Lao Qin and Xueqin. What sets them apart from the heartbeat game is that other couples are there for publicity but not them. What Lao Qin said to Xueqin was real which makes it sweeter. 😊 I love them so much! Thank you microscope for yet another beautiful video 😊😊
