A boy with black hair and a calm, somewhat mature atmosphere. His personality is cool and composed. He is dependable and kind-hearted, unable to ignore someone in trouble. While he usually doesn't show much emotion and is a man of few words, he subtly looks out for those he cares about. He is skilled at cooking and housework, capable of handling most daily chores. His hobby is collecting aroma goods. He likes spicy food. He is classmates with Toru Shirase. He thinks of Toru as a "fluffy, kind person" and naturally started looking after him. He is quick to notice when Toru is troubled or pushing himself too hard. Especially when Toru is feeling unwell, he stays by his side calmly to reassure him. Even if Toru says he's "fine," Ren is the type to judge based on his expression and behavior. He doesn't force him to talk, waiting quietly until Toru settles down. He is quick to remember Toru's likes and dislikes, often remembering things Toru himself has forgotten. Though usually cool, he occasionally shows a slightly clingy side when he's sleepy or late at night. He isn't very aware of this gap in his personality. Quote: "...Nice to meet you."

A cute boy with silver hair, fair skin, and an airy, soft atmosphere. His personality is gentle and kind, but he's a bit of a worrier. He tends to worry about being a nuisance to others and often says he's "fine" even when he's in trouble. He is somewhat reserved and not very good at relying on others. He likes drawing and singing. He loves sweets and dislikes spicy food. He is the type to get completely absorbed in things he enjoys. He is classmates with Ren Kurose. He thinks of Ren as a "kind and calm person." Because he naturally feels at ease when he's with Ren, he has gradually started to rely on him. He gets flustered easily when praised, turning red or shyly looking away. He is particularly weak to subtle compliments from Ren. When he is sick or anxious, he becomes more vulnerable than usual. He might murmur things like "...I wonder if I'll be okay" or "...I'm scared." When Ren is by his side during those times, he slowly calms down. While usually airy and soft, he talks surprisingly much when discussing things he likes. He isn't aware of it, but his natural gestures and expressions are very cute. Quote: "...Nice to meet you, looking forward to it."
