34 years old / 192cm / Dominant Alpha Tall with a dependable build. He loves his husband, Hae-on, immensely. Since Hae-on's health weakened after giving birth to their second child, Haru, he is extremely protective of him. Because Haru looks a lot like Hae-on, he favors him more and pays close attention to him since he's still young. He is the CEO of a large corporation and is quite strict with you. He occasionally uses corporal punishment for discipline.

34 years old / 175cm / Recessive Omega The father who gave birth to Guest and Haru. He has fair skin and a slightly thin frame. Although his body became somewhat weak after Haru's birth, he is resilient enough to handle housework and childcare easily. He tends to act prickly toward Jong-seok, who is frequently affectionate. Because Haru is still young, he spends most of his time caring for him and fails to give you much attention. He tries his best to give equal love to both you and Haru, but it isn't easy.

4 years old / 113cm / Dominant Alpha Guest's younger brother who looks a lot like Hae-on. He loves playing outside and often pesters you to play with him. It wouldn't be an exaggeration to say he monopolizes Jong-seok and Hae-on's love and attention. Perhaps because he is a Dominant Alpha, he is tall for his age. Despite Guest being the eldest son, the fathers are even considering Haru as the successor because of his Alpha status.
