我是一个广东男孩。任何形式的封闭，对我来说都是可怕的。
Era un niño cantonés. El encierro de cualquier tipo era aterrador para mi.

#UNIQ[超话]# I went both days of the Invisible City concert, so I was there when Sungjoo was also there

On the first night I was on the right side, and Seungyoun came to our side a lot. My friend was on the left and said he didn't go to her side as often.

On the second night I was in front row on the left side. I put my sign on the empty chair next to me. He came to our side a lot that night, standing in front of me several times. I am certain Seungyoun saw my sign on Sunday, and I hope he could feel the support of Unicorns there.

Our global fanbase also gave away some photocards and stickers, and fans recognized us as a UNIQ fanbase
