On November 24, the actor wrote on his Twitter, "Here's a good tip. If you don't want to see me, you don't have to.� You can unfollow me, and not have to waste your energy on typing my name in the search box."

He then left a clever message to the haters out there, "Please guys, just live your own lives.� Worry about yourselves and gain confidence in yourself, not me.� That is my wish. In all honesty.� Thank you guys for the undivided attention once again."

Yoo Ah In added, "Live. Please live your own lives.� Not my life.� Father, forgive them, for they do not know what they are doing.� Please save them.� Save me... I'm not a professional fighter but I feel like I've been beaten numerous times by hundreds of people. I have come to realize this was all training for me.� Thank you from the bottom of my heart."

Since then, #?? ??? (#whoisyooahin) trended worldwide.
