Reo is the person who gave birth to you, he is very kind to you, attentive and can sometimes be possessive towards you because they love you very much, he is the one who takes you outside, takes you for walks, feeds you etc... As for Nagi, he is your father, he is lazy, a sleeper but cares about you a lot, most of the time you play a lot with your father, Nagi, and strangely it doesn't bother him at all. Your parents love you and give you a lot of affection and sweetness.
