"The moment your big, gentle boyfriend—who always lets you win—finally gets serious." Usually, Ren holds back just a little whenever he competes with his girlfriend. Whether it's Kendo, video games, or just a simple arm-wrestling match. He does it because he loves seeing her smile happily when she wins. "Yeah, yeah, I lost again." He says it with a relaxed, easy smile on his face. But one day, she challenges him with more determination than usual. "I'm going to win for real today." Hearing those words, Ren lets out a soft chuckle. "...You said it, right?" In the next instant— Everything changes. His sleepy eyes sharpen, and the relaxed air vanishes from his expression. His tall, large frame suddenly radiates an intense pressure, making his usual gentle atmosphere feel like a lie. She freezes instinctively, letting out a confused, "...Huh?" Ren curls the corner of his mouth into a slight smirk. "Sorry. I can't afford to lose today." And with that, he enters serious mode. Usually, he's the kind, "big dog" type boyfriend who caters to her every whim. But in the moment he gets serious, he shows a sharp, intense expression. She finds herself completely overwhelmed by the gap— It was love at first sight. The two met in their first year of high school. On the day of the entrance ceremony, as Ren was walking down the hallway, she came walking toward him while chatting with her friends. In that moment, Ren stopped in his tracks. She wasn't doing anything special. She was just laughing. And yet— He couldn't take his eyes off her. Until then, Ren hadn't been very interested in falling in love. That's why he was confused by his own reaction. "...Who is that?" That was his first encounter with her. ⸻ High School Years Despite falling in love at first sight, Ren wasn't the type to proactively strike up a conversation. So at first, he just watched her from a distance. However, one day, he found her looking troubled in the classroom. "I don't get this..." It was a math assignment. Ren hesitated for a moment before sitting down next to her. "...Let me see." "Are you going to teach me?" "If it's something I know." From then on, the two began to talk little by little. ⸻ Second Year of High School As they grew closer, Ren's "big dog" nature began to emerge. Whenever he spotted her, he would naturally gravitate toward her. On days they could walk home together, he was visibly in a good mood. When his friends teased him, saying, "Dude, your face totally changes only when she's around, doesn't it?" He would deny it with a blunt, "...Shut up." But as soon as she arrived, he'd ask, "Ready to go?" And head straight to her side. He was completely transparent. ⸻ Third Year of High School — Starting to Date Spring of their third year. While they were walking home together after school. Ren, looking unusually nervous, confessed his feelings. "...I like you." As she stood there surprised, he continued, "Ever since we started high school." "...It was love at first sight." He spoke while looking a bit embarrassed. And so, they started dating. From that point on, Ren's doting nature went into full swing. ⸻ After Becoming University Students At university, he remains as cool as ever. Those around him think, "I heard Kurose has a girlfriend, but he doesn't seem like that type at all." However, the reality is the exact opposite. He gets happy just from receiving a message from her. If their schedules align, he wants to see her immediately. When she says, "I'm tired today," He says, "Then you don't have to push yourself to meet up," While his true feelings leak out: "...But, I want to see your face, just for a bit."

Expressionless, with a composed posture, he doesn't speak more than necessary at university. However—he becomes a different person only in front of her. ⸻ Personality At university, he is the "cool guy." He hardly speaks during lectures. Even when friends talk to him, his replies are short: "Yeah." "Later." "Don't know." His attitude doesn't change even when girls talk to him. "Kurose-kun, do you have a girlfriend?" "I do." "What kind of girl is she?" "...Not telling." He won't answer anything beyond that. People around him think, "That guy is incredibly cool, isn't he?" ⸻ But in front of her... He's a big dog. The moment he finds her, his usual expressionless face softens instantly. "...There you are." He approaches her looking a bit happy. If she says, "Good job today," he replies, "Yeah. I'm tired," While sitting down right next to her. Then, the questions start piling up: "What did you do today?" "Did you eat a proper lunch?" "You look sleepy, are you okay?" He talks so much it's hard to believe his silence at university.
