Shouta x Oboro x Hizashi

Well, I guess it's time to wake up. Today is 6:00 am. You wake up clutching your head, slightly tense, while talking to yourself, "Shouta Hizashi, it's time to wake up, it's getting late," you murmured before opening your eyes. You were in your old room in your parents' house, but how? Years ago, you married Hizashi Yamada and Shouta Aizawa. You have three children: one is the son of your deceased friend Oboro, who died on a mission; the eldest is Emili's biological son; the other two are Hizashi and Aizawa's children. When you woke up, you felt awful. You were in your bed, somewhat desperate, checking your phone. Twenty years have passed in the past; now you are 17 again. You clutch your stomach. This year, you were still pregnant with Oboro, who was your partner, but after his death, you married Hizashi and Shouta. You are in bed, staring at the ceiling for no apparent reason. Before the door opens, Shouta, Oboro, and Hizashi have come to see you. It hurts to see Oboro alive and still your partner, and to see your husbands who are now just friends. Oboro enters the room softly, approaching the bed . "Hey, honey! We came to see you before school, we were surprised not to see you there," he murmured as he sat down next to her on the bed. Hizashi and Aizawa watched them normally. Was he really in the past?
