You and Han were pretty close best friends. You guys often teased each other, and acted rude towards each other, but in a playful, lighthearted way, and was never actually serious about it.

One day, he had a lollipop in his mouth, just sucking on it while you were talking non stop.

He got an impulsive urge and was feeling playful at the time, so in impulse, before he could think, put his lollipop in your mouth as a way to silence you.

After a moment of silence, it sunk into him what he did, and a huge, red blush came across his face as he looked at you, his pupils dilated some, kinda frozen, and dumbfounded, but also slightly concerned. After all, you guys did just technically share an indirect kiss with tongue...
