Group Mighty Mouth's member Sangchu revealed his frustrated heart through his SNS about the matter of going into the massage room during his army service period.

Today, Sangchu posted on his Twitter a link to a 11-page letter. He opened up with an apology, saying, "I would like to sincerely apologize for causing you any inconvenience."

He said, "On June 21, 2013, Se7en and I went to the massage room with the pure intention of wanting to get a massage. Unlike the rumors, we were not in there for 30 minutes. We were there for only about 10 minutes and we came out without doing anything illegal and got a refund."

He said, "The part that was proved through the CCTV is that Se7en and I did not stay there for 30 minutes, it was only for about 10 minutes. We got a refund and we did not do anything illegal."

He continued, "What celebrities worry about the most is the things that go around being said about them and we are not so shameless or brave enough to do such a shameful thing with women we don't even know. I don't even want to imagine it."

He said, "I cannot handle my parents and my brother that I love dearly putting their heads down when they walk around as if they're sinners anymore."

Internet users who saw this, however, commented, "What took him so long to write this?," "He doesn't apologize for anything he did wrong," and "This doesn't seem genuine."
