It's not unusual for fandoms to rent out ad space for special events like birthdays and anniversaries, but TWICE have flipped the script by renting a subway ad to thank ONCEs!
The "TT" hitmakers posted a special message to their loyal ONCEs on their 2nd anniversary to thank them for their support.
"I am not sure if you are having a good day, or a bad day, having the same busy daily routine, or you're having a hard time and feeling worn out," reads the message.
"But we had prepared this to ONCE and want to cheer you up even if it's just a little bit. This is a lot more lacking than all the present gift-like thing you have done for us throughout this 2 years, but we will work harder towards the day where we can repay all back to you."
