IV: Ko-ki's Birthday (1 May Twitter)

Mitsuru:
Ko-ki's birthday.
Most probably I'm the first one wished him
as I called him few minutes before birthday (laugh)

Before becoming members we are friends
will be friends forever
Support him in new road (of career)

Happy birthday!

(Note: Since IV changed his username to MTR, I will use both Mitsuru and IV when updating his tweets.)

こーきの誕生日
多分俺が一番最初におめでとう言ったよ。
誕生日数分前に電話してたから笑

メンバーである前に友達だった
これからもずっと友達
新しい道も応援してる

おめでとう！！
