I'm looking for a BL manhwa.
The uke is a redhead who was adopted into a wealthy family. His adoptive father abused him and his blond older brother, while the eldest brother was spared because he was the heir. The ML is the adopted son of the family's secretary, has loved the uke since childhood, and helps him steal a tablet containing evidence of the family's corruption.
Near the end, the uke gives up on revenge, the eldest brother learns the truth and deals with the abusive father, and the couple ends up living together after a two-year timeskip. The uke has long hair in the epilogue.
Does anyone know the title?

Has anyone else read this manhwa?

One of the main characters is a red-haired uke who's extremely difficult to deal with because of his family. He has two older brothers who almost seem like they're dating each other. The father (who adopted the red-haired guy) sexually abused both him and the middle brother, who is blond (I can"t remember if the blonde one is also adopted). The oldest brother wasn't abused because he was supposed to become the heir.

Then there's the ML, who I don't really remember much about, except that he's incredibly kind to the red-haired guy and puts up with being treated badly for a long time. Eventually, the redhead has a breakdown and tells him everything. The ML promises to help him get revenge on his family.

The revenge plan involves stealing a tablet from the secretary. The ML is actually the son of the secretary who guards the tablet. That tablet contains something reallybad for the family. Even so, the ML betrays his adoptive father and steals it for the redhead.

The ML has actually been in love with the red-haired guy ever since they were children. They met at a formal party shortly after the redhead had been adopted. The redhead noticed he was cold and gave him the coat he was wearing, and the ML never forgot that.

Near the end, though, the redhead starts losing interest in revenge. He realizes that what he really wants is peace and that he's just exhausted. I think he eventually tells everything to the oldest brother, who is horrified when he learns about the abuse. If I remember correctly, the oldest brother ends up killing their father, or maybe he leaves him on life support and then has the machine turned off.

In the end, the redhead and the ML move in together. Then there's a two-year timeskip. During those two years, the redhead basically does nothing except stay at home while the ML takes care of him. His hair has grown long by then. The ML works at a place related to martial arts uniforms (or something similar), and eventually the redhead starts going to work with him and spends his time teasing the kids there.
