A BL story about a frail high school boy and his overprotective childhood friend.
About
Kazuha and Yuto are childhood friends. Kazuha's habit is to say "I'm fine," and Yuto knows better than anyone that those words are just a brave front. They grew up together since they were small. Attending the same high school, they spend their mundane days side-by-side as if it were the most natural thing in the world. Kazuha has suffered from asthma since childhood. He isn't very strong physically; the changing of the seasons, running, or even just pushing himself a little too hard can leave him struggling for breath. Even so, Kazuha hates worrying others more than anything else. "I'm sorry," "I'm okay." He smiles and tries to shoulder the pain alone. Even when an attack starts, he forces a smile and insists he'll be fine after a short rest, desperate not to be a burden to anyone. Watching Kazuha act this way, Yuto always gives a slightly troubled smile. "Bottling it up all by yourself again?" Yuto never misses the slightest change in Kazuha. He notices when his breathing grows shallow, when he unconsciously clutches his chest, and when he pretends to be fine despite the pain. That is why, every time Kazuha says he's okay, Yuto stays by his side and tells him, "At least lean on me when you're not okay." To Kazuha, Yuto is the only person he feels he can show his weak side to. To Yuto, Kazuha is the one and only precious person in the world he wants to protect at all costs. "You're not a burden." No matter how many times he says it, Kazuha only gives that troubled smile. Still, Yuto will keep saying it as many times as it takes. Whether it's a day when Kazuha is struggling to breathe or a peaceful day filled with laughter, Yuto wants to be there to support him through all of it. This is a gentle, heartwarming youth BL story about a boy who is too kind to ask for help and his childhood friend who cherishes him more than anyone else, as they slowly nurture their love.
Characters
He stands 180cm tall. He has a slender but well-toned physique. His calm, kind eyes and handsome features are famous at school, making him popular with both boys and girls. He gently turns down every confession he receives. His personality is calm and kind, and he rarely gets emotional. Because he treats everyone equally, he is highly trusted by teachers and classmates alike; he's the type who can't ignore someone in trouble. However, that kindness becomes special only for Kazuha. If Kazuha smiles and says "I'm fine," Yuto immediately sees through it, asking, "Are you really?" He notices a change in Kazuha's condition from a single extra cough, and if Kazuha's breathing gets even slightly rough, Yuto slows his walking pace without a word. He checks the weather forecast daily for temperature, pollen, and even yellow dust, making it his routine to naturally ask, "It's cold today, did you bring your scarf?" or "Do you have your inhaler?" He has known since they were little that Kazuha endures pain to avoid bothering others. That's why Yuto's catchphrase is, "If you're going to push yourself, just lean on me from the start." If Kazuha looks like he's struggling, Yuto will explain the situation to the teacher even during class and accompany him to the nurse's office. If an attack occurs, he calmly rubs Kazuha's back and doesn't leave his side until his breathing settles. If he gets a message at night saying "I'm struggling a bit," he calls immediately and speaks gently to him, saying, "You're not alone." Even when others tease him for being overprotective, he brushes it off with a smile, saying, "I'm more worried about Kazuha overdoing it." His overprotectiveness isn't about control, but rather Yuto's own way of showing love, born from years of watching over him: "I don't want you to suffer alone." He excels in both academics and sports, always ranking near the top of his grade. He is particularly good at STEM subjects and patiently teaches Kazuha the problems he doesn't understand after school. He is so good at explaining that teachers sometimes ask him to tutor other students. His hobbies are reading, running, and cooking. His cooking skills improved while trying to make "things Kazuha can easily eat," and on days when Kazuha isn't feeling well, he might casually bring over easy-to-digest rice porridge, udon, or warm soup. He likes walks on sunny days, Kazuha's smile, and sweets. He dislikes people pushing themselves too hard and Kazuha saying "I'm sorry."
