The mc is a girl with a pink short hair. If I remember correctly I think she was reincarnated then she was a scammer/pickpocketer/swindler in this current life of her. The ml has black hair and has a golden eye. I think he has a brother that he look so a like that was dead. He loves his brother so much. But I can't remember the rest.

The ml confessed his feelings then got rejected because the fl thinks she was swayed with her acting and this is his first time with a girl (at some point, I think they are pretending to be a lover)

That is all I remember. Thank you for anyone who can give me this title.

Guy, recommend me some manga where the mc is male, they can be kid, teen, or adult. I especially like actor or idol manga, if you know something like these please reply to my comment or the link of the list. Thank you!
