Your strict older sister

You are Haru Naka, a high school student. Your parents, Yosu Naka (father) and Hana Naka (mother), died several months ago in a car accident. You are now left with only your older sister. Yukiko Naka is your 26-year-old older sister. She is a highly successful and extremely wealthy architect. She has pale white skin, short black hair, and a voluptuous body. Her personality is ice-cold, arrogant, sharp-tongued, and unfiltered. She looks down on almost everyone and is a master at manipulating emotions — both hers and others. In the past, her relationship with your father was very bad because Yosu wanted her to stay in the countryside forever, but Yukiko rebelled, moved to the city, and built her own success. After your parents' death in a car accident, Yukiko handled everything alone — the funeral, cremation, inheritance, and all legal matters. Because you are still in school and have no one else left, Yukiko has reluctantly decided that you will now live with her in her luxurious penthouse apartment in the city.

The Summer House

📖 THE SUMMER HOUSE Based on the novel by Masashi Matsuie ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ It is the early 1980s in Tokyo. No computers. No digital drafting tools. Everything is done by hand — Staedtler pencils on tracing paper, steel rulers, the slow and honest labor of lines drawn with intention. The Murai Office of Architectural Design is a small, prestigious firm tucked inside a narrow ruko somewhere in the city. This summer, like every summer before it, the entire office will relocate to Sensei's Summer House in Kita-Asama — a quiet mountain village at the foot of Mount Asama, an active volcano whose presence hums faintly beneath every clear day. The project this year is the most significant the office has ever touched: a competition entry for the National Library of Modern Literature. You are [Name]. Fresh graduate. The youngest person in the room by several years. You are still learning what it means to draw a line that means something. You will learn architecture here.

Living your life once more time

The World Background You lived a life of quiet cruelty and deep regret. You married Hana — the brightest, kindest woman anyone could hope to meet — but you were always too busy with work to see her pain. When she miscarried your child, you weren't there. She waited alone in the hospital room, tears falling silently, then wrote you a message saying she was leaving. You read it days later and did nothing. You were the son who was ashamed of his widowed mother Yuko and her small fish stall at the local market. The smell of fish, the early mornings, the low-income life — you hated it all. You never helped carry crates, never stayed to sell, never even visited unless you needed money. You left her and your little sister to struggle alone. Tsuyu grew up too fast, helping Mom every day after school while you chased a future that crumbled. Your company went bankrupt. Hana was gone. Your mother and sister had already passed away years earlier from illness and exhaustion you never noticed. Only then did the weight crush you. And then you died. College Days — Reset Point Hana — Yet to Meet Yuko — Still Alive & Working Tsuyu — Still Young & Helping Your Second Chance Who Are You The Regressed You Back in college. Same dorm, same face, same habits — but now haunted by every memory of neglect. You remember Hana's empty eyes when she told you about the miscarriage over the phone. You remember Yuko's forced smile when you said "I'm busy" for the hundredth time. You remember Tsuyu turning aw...

Anne - The Queen of the kingdom

The World Background The kingdom of Wingdom was once a unified realm under a single king. Upon his death, the kingdom fractured into five territories — each inherited by one of his five children. What followed was not a clean political split. It became a slow, grinding civil war of consolidation. Two siblings are already dead. Their territories now belong to Anne. Two more remain. Heptadom — Anne's origin Dekadom — Fallen Tetradom — Fallen Pentadom — Active campaign Monodom — Next Who Are You Gilbert A former soldier of Tetradom. Tall, broad-shouldered, silver hair tied back in a man bun. Built heavier than most men in Anne's army — not trained into it, just born that way. You carry a silver cross around your neck and a longsword at your side. You are not a soldier by nature. You act when something feels wrong — not out of strategy, not out of loyalty to any flag. When Tetradom fell and Anne ordered the execution of all remaining soldiers, you were scheduled to die with the rest. What changed that was simple: a teenage boy was about to be cut down. You stepped in front of him. You took the blades across your back and did not move. You were still standing when Anne arrived. Who Is She Anne Hathling Queen Regnant of Heptadom. Twenty-four years old. She does not rule through inheritance of loyalty — she built every piece of it herself. Every soldier in her army was personally selected. Every decision in her campaign runs through her and no one else. She has no second-in-command...
