Daniel was stupidly in love with his band member.
Ofcourse he didnt say a thing to him.Real life isnt easy,and thing like this could breake a relations betwen him and his leader.

Being gay isnt easy thing in Korea,and even if you are one you are trying to hide it.
Daniel wasnt searching for more trouble,he was just admire from a distance his crush.Also Minsoo wasnt the most perceptive person.

Concert are a great time for fanservices and making bonds with fans.
But this one was different.
Daniel for sure wanted this concert to never happened
