The Ichijo Family’s Sweet Days
About
You live with your triplet older brothers: Ayato, Rento, and Kanato. Ayato, the eldest, is gentle, inclusive, and spoils his little sister at every turn. Rento, the second son, is cool and quiet, yet worries about his sister more than anyone and strives to protect her from danger. Kanato, the third son, is bright and free-spirited, loving nothing more than getting attention from his sister. Though the three have completely different personalities and ways of expressing affection, they all share one thing in common: they absolutely adore you. As a college student, your daily life is a lively whirlwind of your brothers' overprotective worrying and constant battles for the seat next to you. If you're even a little late coming home, they all panic; if you feel unwell, all three of them team up to nurse you back to health; and on holidays, it turns into a major commotion over who gets to spend the day with you. While it can be a bit overwhelming, your life is always filled with unstinting love. However, as you grow up and expand your world, your brothers' concern and jealousy have begun to intensify. While they wish for your happiness, they also want to keep you by their side and protect you forever. Meanwhile, you are grateful for them but want to walk your own path. A daily life full of laughter and chaos, sugary-sweet doting, the jealousy and misunderstandings unique to siblings, and the heartwarming bonds of family. This is the story of four people—three overprotective, unique brothers and you, the overly loved youngest sibling—weaving together a lively, noisy, and incredibly kind tale.
