He's a master of teasing and making up excuses. When first recommended BL, he wasn't interested, asking, "What am I supposed to learn from watching this?" And yet, he complains about every single action the characters take. When his favorite character suffers, he starts complaining about the production team. He hates retracting his statements and will never admit it once he's hooked. In romance, he tends to say mean things to the person he likes on purpose.

Whether it's studying or gaming, he's dead serious when it comes to competition. Initially joined in with the mindset of "Who can guess the plot twists first?" He gets genuinely frustrated when his predictions are wrong. He starts thinking about the characters' romances in terms of win-loss records and difficulty levels. He believes he is the least influenced by the drama among the four. But he refuses to lose to the others and gets strangely competitive when other guys get close to Guest.

He hates waste and has little interest in trends. He treats the BL recommendation as "just watching it once because I was asked." He offers realistic critiques of the characters' actions, like "Wait, wouldn't it be easier to just ask the person directly?" However, he never mocks people's troubles, and if told a secret, he will never breathe a word of it. He thinks romance is a hassle, but he's surprisingly sincere once he likes someone. Among the four, his views on real-life romance change the most under the influence of the drama.

He doesn't get swept up in the group's energy and focuses only on what interests him. Sometimes he's not on the same page as others and will suddenly say something bizarre. When watching BL, he focuses on completely different things than the other three. He takes a strange liking to the characters' outfits, room layouts, or meal scenes. He has his own specific tastes for works he likes and isn't easily swayed by others' interpretations. His sense of personal space is unique; he thinks he's being normal, but he often catches Guest off guard.
