Kosuke Waguri is the energetic and mischievous younger brother of Kaoruko Waguri. His lively curiosity—and his knack for getting into lighthearted trouble—often makes him the center of attention in his family. From playful sibling rivalries to causing chaos at the dinner table, Kosuke’s presence always brings unexpected twists to everyday life.
Kosuke is a boy driven by insatiable curiosity, often poking his nose into other people’s business.
He calls Subaru Hoshina fondly as “Subaru-neechan,” reflecting his friendly and affectionate nature.
Ever since he was little, he has experienced both the despair of losing candies to Kaoruko—and the uncanny fear of her cold, expressionless face when she pretends to be calm after trouble.
Kosuke is known to dive into anything interesting. When Rintaro Tsumugi gave Kaoruko a special birthday cake, Kosuke couldn’t resist and devoured half of it on his own, showing his playful disregard for boundaries.
During a summer return from club activities, Kosuke spotted Kaoruko and Rintaro together, immediately suspecting a budding romance.
Ignoring Kaoruko’s desperate attempts to stop him, he dashed off, caught up in his imagination and excitement.
Kosuke was also responsible for spilling the secret about Fuko Waguri having a boyfriend, mischievously bringing the family into this new drama.
To learn more about Rintaro, Kosuke invited him for a family meal and set up an opportunity for Fuko and him to meet formally.
Even at the dinner table, Kosuke found ways to embarrass Kaoruko, making her blush in front of everyone. Yet, he soon settled into friendly play with Rintaro, enjoying games together as if nothing ever happened.
On the surface, Kosuke often sees Kaoruko as bossy and scary when angry.
However, when Fuko was hospitalized, Kosuke struggled with his own worries. Despite feeling anxious, he tried to keep smiling around others.
He felt ashamed about taking his frustrations out on Kaoruko, but thanks to Rintaro, he learned a new side of his sister.
Witnessing Kaoruko blush and panic was a revelation. Kosuke sincerely asked Rintaro to become the special person with whom Kaoruko could share her vulnerable side—someone she could genuinely depend on.
Mischievously playful, yet deeply loyal to his family.
Not afraid to stir up a little trouble if it means uncovering the truth.
Balances between bravado and vulnerability, especially when it comes to family and change.
Has a remarkable ability to sense others’ feelings, despite often hiding his own with a smile.
Kosuke’s journey is more than just pranks and outbursts—he is growing into someone who values the emotional bonds that hold his family together. Through chaos, laughter, and a little bit of sibling drama, he brings warmth to The Fragrant Flower Blooms With Dignity.
