I have been searching a manga that I read time ago, but I don't remember the name of it 
This what I remember:
There was this person who is a singer/idol in a group but they are not that famous. So their manager says to like the main character and I think the leader of the group to participate in a show with two other guys, because the person that was going to go got into like trouble, let say, or he did something bad and it even came out on the news. And because of that there was a spot left for the main character, so he decides to go. When he gets to the place where they are going to start the recording (which is a house) he was looking around the house and got to the second floor of the house and he heard some notices (i guess) so he approached the door (which was slightly open) and saw one of the guy that he is going to appear in the show with him giving head to the other guy who he is also going to be with in that show. He was shocked at what he saw and then heard someone going up the stairs. It was a camara man who was recording the house for like the show and he was trying to distract the camara man to not go in the room where the two guys were, because appearing in the show will give him benefits for the group and their growth.But he couldn't stopped the camara man to enter the room, so the camara man enters and starts recording the room. While the camara man was filming the main character was confused on where the two guys went, after he heard a sound from the closet of the room. He immediately knew the two guys were in there. And the camara man was like what was that sound and the main character was making excuses. While the other guys where continuing their business in the closet making more noises that made the main character make more excuses and trying to take the camara man out. He succeeds to take the camara man out after he finishes his filming shoots of the room. And then the main character meets the other two guys and they're acting like nothing happened between those two.
That's all I remember and I hope someone knows the name please I really want to continue reading it.
