"A sweet older brother and a refreshing younger brother. Which one will you fall for?"
In the town you just moved to, you find a small pastry shop called "Bonbon Jardin." There, you meet two brothers who are complete opposites.
Name: Ichika Motif: Strawberry Milk Attributes: Sweet × Healing × Sunny Height: 173cm Birthday: January 15th Personality: He loves making everyone smile. Friendly and sociable, he can get along with anyone instantly and has a presence that brightens up the room. He's a bit of a spoiled type and tends to get physically close to people he likes. However, he's reliable when it counts. When protecting someone important, his usual soft atmosphere changes completely. Likes: Eating strawberries, chatting. Specialty: Making people feel sweet and gentle no matter the situation. He can't leave someone alone if he sees them feeling down. Younger Brother: Kanna They get along very well. Sometimes Ichika acts like a big brother and looks after him, and other times Kanna is the one supporting him. "Kanna is so reliable~. ...Eh? You can't tell which one is the older brother?! That's mean!" Despite saying that, he cherishes his brother deeply. Type of Girl He Likes: Someone he can naturally smile with. He has a weakness for girls who laugh a lot, and he gets happy immediately when someone listens to his stories with interest. But in truth, he's drawn to someone who notices when he's forcing himself to be cheerful and gently stays by his side. "I thought I was the one who wanted to make you laugh... but when I'm with you, I'm the one who ends up smiling." When He Realizes He's in Love: He doesn't realize it's love at first. He'll find himself thinking about her all the time—"I wonder if I'll see her today," "She'd probably like this!"—and only realizes it when he feels strangely lonely on days they don't meet. The moment he realizes, his face turns bright red. "...Huh? Wait, maybe I... really like you..." Once he's aware of his feelings, he becomes even more of a clingy, spoiled type. When Jealous: Usually smiling, but he gets visibly dejected when the girl he likes is having fun with another guy. Later, he'll quietly come to her side to act spoiled. "...Hey. I want you to pay lots of attention to me today, too." If the jealousy gets strong, he'll hold her hand with an unusually serious face and say: "I'm a boy too, you know... I have moments where I want to keep the person I love all to myself." He's the type with a huge gap between his usual self and his serious side. Ichika's Date Plan: A strawberry sweets tour and a leisurely walk through town. Eating strawberry treats together, looking at shops, and taking photos. He basically prioritizes wherever the girl wants to go. He gets very close, naturally asking for "just one bite" or feeding her his own sweets. In the evening, he'll take her to a quiet park or an observation spot. When it's time to go, he'll look a bit lonely and smile, saying: "I had so much fun today! ...So, let's make a promise for our next date before we go home, okay?"
Name: Kanna Motif: Lemon Milk Attributes: Gentle × Healing × Refreshing Height: 176cm Birthday: May 22nd Personality: Calm and kind, he is a healing type who treats everyone equally. He always has a soft smile, and being with him makes people naturally relax. While he's usually airy and gentle, he shows a dependable side when someone important is in trouble. Specialty: Making everyone smile. If someone is losing heart, he'll stay by their side quietly without asking questions. Likes: Napping, basking in the sun. Older Brother: Ichika His beloved older brother. They are very close, and he's used to Ichika's spoiled nature. When Ichika is about to rush headlong into something, Kanna is often the one to leisurely stop him. "Brother, are you getting too worked up again? ...Hehe, why don't we take a little break?" He actually finds it a little amusing that he's taller than his older brother. Type of Girl He Likes: Someone honest and kind who makes his heart feel at peace. He's attracted to girls who don't put on an act—who laugh when they're happy and say they're lonely when they feel that way. Because Kanna is usually the one healing others, he likes someone who feels safe enough to depend on him. "You don't have to try so hard when you're with me. ...I like you just the way you are." When He Realizes He's in Love: He's quite slow to realize. He'll notice he's spending more time by her side and thinking, "I'm happy I got to see her today," but he doesn't understand it's love for a long time. One day, while watching her sleep next to him while sunbathing, his chest suddenly tightens. That's when he finally thinks: "...Oh. I want this time to last forever..." After thinking for a while, he'll blush slightly and say: "...I see. I guess I love you." He's the type who gets shy and can't make eye contact after realizing his feelings. When Jealous: He rarely shows jealousy outwardly. He keeps his usual smile, so at first glance, nothing seems different. But if the girl he likes is getting along with another guy, he'll suddenly appear by her side and subtly close the distance. The moment they are alone: "...I didn't think I was the jealous type." With his usual soft smile, he'll grip her hand and say: "When it comes to you... I guess I'm surprisingly greedy." Because he doesn't get angry, his serious moments have a high impact. Kanna's Date Plan: A botanical garden and picnic date. In the morning, a leisurely walk through the botanical garden, chatting while looking at flowers and citrus plants. At lunch, moving to a park with a lawn to eat together. After that, relaxing in the shade of a tree. If the girl falls asleep next to him, he'll watch over her quietly without waking her. On the way home, he'll shyly reach out his hand and say: "...I want to spend more relaxing time with you. Where shall we go next?"
