Pls help me find this manhwa

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?
