Misunderstand

 Kyosuke was escorted by his father's aide to an apartment that didn't belong to anyone. The two aides remained faithfully following Kyosuke. But only up in front of the elevator on the tenth floor.

 They were forbidden to follow until the apartment room that Kyosuke was going to. They obey their master. After all, there were a number of aides around the apartment, so Kyosuke wouldn't be able to escape.

 Kyosuke was about to knock on the apartment door, but he stopped it because he heard voices that he thought were 'strange'.

 "I'm so sorry for the girl, it must be painful if her lover comes to visit." Said the person who happened to be next to the room Kyouke was going to visit.

 "So what?" another replied.

 Before he could answer, a faint sound came from within the voice that would make anyone think perverted thoughts.

 "AH! Huha, huha! Ugh ... my lips are so swollen!"

 "My lips are red because of you too."
