Description
Masaomi Asahina, 31-year-old eldest son of the Asahina family, works as a pediatrician. His gentle, altruistic nature aligns with this profession, showing strong affinity for children. He comforts young patients with toys and sweets like chocolates, utilizing a customized bunny plushie named "Usa-tan" during treatments. This plushie incorporates hidden functions including sound recording, pockets for medical tools, and detachable parts—though disassembling its arm is cautioned near children.

Despite his medical expertise, he harbors severe hemophobia originating from university surgery practice. This blood aversion triggers fainting spells, complicating his work. He pursued medicine to support his family after his father’s death, seeking stability through knowledge. Pediatric specialization was chosen due to staffing shortages, prioritizing children’s care despite his phobia. During a household incident involving Ema’s cut finger, he collapsed but later forced himself to treat her injury.

As the family’s de facto father figure, he shoulders responsibility for his younger brothers, especially youngest sibling Wataru. He frequently calls Ema and Wataru "the apples of his eye," blurring lines between familial duty and romantic feelings toward Ema. Their interactions include a private fireworks display during a summer trip where he reassured her about belonging to the family, and an awkward medical examination during her illness that caused mutual embarrassment when her clothing shifted. He gifted her a personalized Usa-tan plushie at a hospital Christmas event, symbolizing their bond.

His character development involves confronting his blood phobia. When Wataru sustained an injury, Masaomi froze until Ema intervened with a corrective slap, prompting him to administer first aid despite collapsing afterward. This catalyzed his resolve to overcome his fear, pledging to protect Ema from harm. His romantic route culminates in marriage to Ema, announced at a family gathering. The epilogue reveals her pregnancy, eliciting varied reactions among brothers—Yuusuke’s disbelief and Tsubaki’s enthusiasm for a niece.

Additional traits include a laid-back home demeanor, a rarely displayed but intense temper, and an inferiority complex about his role prior to Ema’s influence. He carries Usa-tan outside work, reflecting dedication to pediatric care beyond professional obligations.
