It's typical bl manhua when the mc is weak omega actor married popular cold alpha. The alpha always have trust issue with everyone especially to mc. He think mc married him only for the wealth, but after many month?? Or years he start getting warm to the mc. But the alpha ended found the mc having affair (it's misunderstand) and straight up kick him from house without knowing the mc is pregnant with his kid. The mc ended living with his omega dad who actually had similiar issue with his son i remember both of them worked in flower shop. And then i forgot the rest of story ╥﹏╥
