Review Detail of serenaluna in Empty Promises: The CEO Cunning Bride

Really curious about their past lifes and what really happened. Was there a misunderstanding or plot? My guess is the ML tried to trick his family and pretending by hurting the FL in front of his mom and that other girl. But he didn't realize it hurt the FL so much and made her killed herself. I guess why he wore red suit for a groom, because he wanted to surprise her by replacing the said groom, but he's too late because she's dead already. Or he heard about the suicide news and then 'kidnapped' the body. Later, because he couldn't accept the reality, he tried to make a (ghost) wedding with her(?) to fulfill his wish. Wonder who else remember their past lifes. Ah, this is so heartbreaking. It made me crying in many chapters.
