Ok the bidders find out MC has an identical twin.

logielouu:

Eisuke: Would they notice: Yes. Within the first few seconds of meeting your twin he would ask who you were, why you were there and where the real you was.

Soryu: Would they notice: Yes. Walking into his apartment and seeing the look alike sitting on the couch he immediately drew his gun, panicked to where you were and what happened to you.

Ota: Would they notice: Not at first. He didn’t really pay your look alike much attention as he was immersed in his work. But when your twin hugged him from behind he snapped out of it, jumping back and taking a good look at you, realizing you weren’t you. 

Baba: Would they notice: No. He would kiss and cuddle you as your twin giggled in his arms, for other reasons. When you popped up from behind and caused him to freak out did he realize that it was your twin, and not you, he was with.

Mamoru: Would they notice: Yes. Even though he was lazily sleeping on the couch, you touch wasn’t the same. It was unfamiliar, awkward, unpracticed. Opening his eyes and seeing someone look into his face, he flipped your twin over so he was pinning her down, “Wheres Khim!?” He asked, until you appeared behind him laughing away. “Tsk.”

Luke: Would they notice: Yes. One look at your twin was enough to prove to himself that she was a fake, “Your not sexy bones.” Was all he would say before turning around and walking away, trying to find you.

Hishikura: Would they notice: Maybe. If he was working and to busy to look up, he would have thought it was you making him coffee. But when you brought out the expresso at the perfect taste he stopped, finally looking up and realizing the woman walking around the house wasn’t him, “Who are you?”
