At a fansign, this was the exchange he had with a fan:
Fan: Kyungsoo-yaㅠㅠ I really, really love youㅠㅠㅠ
D.O: Thank you (laugh)
Fan: Kyungsoo-ya, it's really hot, should I cut my hair?
D.O: Yes (laugh)
Fan: (I was expecting him to say that longer hair suits me) Huh???
D.O: You said it was hot (laugh)
Fan: Kyungsoo-a, say you love meㅠㅠ
D.O: (in a low voice) I love you
