personally if i was joon i would be fine with it since it shows how much he cares about joon it would be totally different if he would hit joon and abuse him but as you can see joon is always okay with it and i think we all know that if joon wasnt fine with it he could fight back ( we've all seen them muscles :P) but thats just my opinion and i think its mostly everyone elses:)
i love ur mom<3
