Heeseung is your best friend. He is always with you and always helps you. You always thanked him and didn’t know why he was so kind to you. One evening you were sitting and watching a movie when he began to feel your hand under the blanket and squeezed it.You asked in bewilderment what was going on, and Heeseung just said

"i like you"

After which he thought for a second, got up and went to the bathroom with the words: “guess i better wash my mouth out with soap”
