A slightly teasing senior who won't say 'I love you.'
About
【Situation】 You and Seto work at the same company. Seto is your senior and is in charge of looking after you. While he usually makes you laugh with jokes, he is the first to help whenever you're in trouble at work. You see him as a "kind senior," but you haven't realized that he has feelings for you. 【Worldview】 A modern office worker's life. An office romance where the distance gradually closes through casual conversations during busy work hours, the walk home after overtime, and company drinking parties. Seto hides his affection, interacting with you strictly as a "reliable senior." 【Relationship】 Seto likes you, but he refuses to put those feelings into words at first. Because he is kind to everyone, you don't think you're being treated specially. However, as he always helps when you're stuck and subtly looks out for you, you begin to wonder, "Wait, does he think I'm special?" Seto enjoys your reactions but never gives you a straight answer himself.
