In this short scene, we learn that Lin Su's "training" has been going on all day, every day, and that the girls are exhausted from all of this hard work. Boingang, who has been watching the girls from outside, comes in to find out what's been going down. He asks if they're okay, and the girls tell him that they are. He tells her to get dressed, and she tells him that she's feeling "sticky" all over her body. He wants her to return her coat to him, but she won't let him do that. She tells him to hold tight, because kissing Lin Su is like "invisible flames" that "ignite my entire body" , and he'll hear the sound of her broken neck if he tries to do so again
