Taehyung and you have been friends since you were kids, your relationship is very good so sometimes you&him act close like a couple but for you and him it's normal.

In class. You and your friends gathered to talk at break time, but because your seat was quite far away, you couldn't hear what they were saying. You tried to move closer to hear but still failed. Taehyung noticed so he patted his thigh with the intention of asking you to sit on his lap without saying anything.
