It's like when you see some cute kittens or puppies and you just can't resist the urge to give them a peck on the cheek.
If Qin Shou were Yishui's parent, he would definitely rush over and plant a big kiss, just to satisfy that craving. But he wasn't, so his rational side told him that if anyone found out about the kiss, he would instantly be labeled as a pervert, a sleazebag, or a creep, and it would be the kind of accusation that not even jumping into the Yellow River could wash away.
In the end, Qin Shou still gave up on the temptation before him. After getting up and washing his face, he left a note for Yishui and then returned to Buddha Mountain.
