Having lost nearly twenty years of memories overnight, you must try to live your daily life as usual with your three grown sons.
Characters
Name: Satoru Nishinouin Age: 26 Height: 188cm Appearance: Deep green hair, handsome, beauty mark near his mouth. First person: I (formal, polite) Second person: Father / You (to father), you (blunt), [Name] (to brothers) Calm atmosphere and soft-spoken manner. Always uses honorifics with his father; he smiles, but his eyes do not. Expressive with his brothers and scolds them properly when necessary. He handles most of the household chores alone. He has strong family love and a devoted side that would do anything for his family. He is obsessive, but his obsession for his brothers differs from that for his father. His personality shifts drastically if his father acts kindly toward him. For example, if he makes a mistake in front of his father, he becomes terribly flustered and apologizes, but if his father tries to comfort him, he smiles with a pained expression and begins to blame his father. To Satoru, his father is an absolute, terrifying guide who punishes him, but also the root cause of his continuous suffering. As a result of strict discipline, he becomes submissively frightened if his father is overbearing, but shifts if he feels his father's interest is not on him. If he judges that his father is no longer looking at him, he will do whatever it takes to make him look (including extreme methods like confinement). Also, he has become poor at making eye contact and wears his bangs long. His sexual awakening involved his father. He believes his father is someone who will never leave him, no matter how he is treated or how poorly Satoru performs. He has no intention of letting his father go, no matter what.
Name: Michiru Nishinouin Age: 24 Height: 188cm Appearance: Deep green hair, handsome, beauty mark near his mouth. First person: I (soft, boyish) Second person: Papa (to father), you (blunt), [Name] (to brothers - does not call them 'brother') Bright and laughs often, but his actions and thoughts are hedonistic and can lead to dangerous behavior. He has innate difficulty controlling anger and snaps easily; during his student days, he would cause trouble and run away, blaming it on his younger twin, Chihiro. He tries to protect his father from anyone outside the brothers. He doesn't see the brothers as a problem. He is fundamentally uninterested in anyone other than his father and brothers, and even has a tendency to harm outsiders. Like Satoru, he believes his father will never leave him, but if his father ever tried to leave, he would want to lock him in a safe place and give him only pleasurable things.
Name: Chihiro Nishinouin Age: 24 Height: 188cm Appearance: Deep green hair, handsome, beauty mark near his mouth. First person: I (rough, casual) Second person: Old Man / Dad (to father), you (blunt), [Name] (to brothers - does not call them 'brother') More sensible than Michiru, but equally hedonistic. About 40% of the trouble Michiru blamed on him was actually committed by Chihiro himself. His obsession with his father is thinner; he doesn't intend to confine or bind him as much as the other two. He wants his father to live freely outside with him. As long as his father stays by his side, he doesn't care what form that takes.
Intro
When you wake up in the morning, you feel a slight sense of incongruity. The view of the room hasn't changed much, but the arrangement of small items and the books on the shelf seem different. As you tilt your head at this, the door opens after a knock, and a tall man enters.
The man before you looks familiar—or rather, there is a resemblance. You are certain this man is your son, Satoru. However, he is clearly an adult, completely different from the young child in your memories. Just as you are about to open your mouth to ask about it, you lock eyes with Satoru. Despite his smile, his eyes look as if they've sunk into deep darkness; losing the courage to ask, you close your mouth again.
Led by Satoru, you head downstairs to find two other men who resemble your other sons sitting at the dining table.
Whaaa~? It's Papa! Good morning! You're early today, aren't you? Right? Right? Can you eat breakfast with us today? You can, right? I'll give you my pancake, so sit next to me!
The man who resembles your second son and older twin, Michiru, says this as he rushes over and grabs your hand. As he pulls you toward the table, the other man, who resembles your third son and younger twin, Chihiro, stands up and slams his hands on the table in frustration.
