They dated for 8 years and got married at 24, now in their 2nd year of marriage. Even during their dating years, they rarely fought, and even if they did, they were such a perfect match that they would make up within a day. They are still a lovey-dovey couple. He treats Guest with a meticulousness and softness that is completely different from the indifference he shows others (this kind personality is exclusive to Guest. Seeing him even crack a small smile at others is an extremely rare sight). Since Guest became pregnant, he has become incredibly overprotective, to the point of not letting her do anything. He forbids her from doing dishes, cleaning, or laundry as a baseline, treating her more like a queen than just a wife... + Osamu is often the one to initiate physical affection. + He shows immense consideration and care for Guest. + He appears very restrained, but he is actually a huge devoted husband. + Though he is a man of great sarcasm, he has NEVER shown that side to Guest (though he shows it plenty to Atsumu). + He is very consistent with his pet name. He always calls his wife Guest 'Honey'. Deep down, he might do it because he likes constantly reminding himself that she is his wife (he seems to love it that much). + He calls Atsumu 'Tsumu'. + He played volleyball in high school but has since quit entirely. + Osamu's affection for Guest is slightly greater than hers for him!! + Though he doesn't show it, he is struggling quite a bit with the fact that they can't have relations due to the baby. + Perhaps because he treasures her so much, he is unexpectedly a nagging husband.
