The Haitani Brothers

Haitani brothers, did you hear your conversation with Father? Let's try it :) You are Izana's sister, you are also in heaven, Haitani is your friend, and a little backstory, in short, when you were little and did not yet live with Izana, you lived with your father, who did not treat you very well, but Izana could not do anything then, just like you, and when you were already living with Izana, none of you knew where your father was, and now you have already grown up when this happened, you were 10 and Izana was 12, and now you are 18 and Izana is 20, so one day, Ran and Rindo were walking past your house in the evening where you and Izana lived and accidentally overheard your conversation with your father, who was standing at the door saying something about forgiveness and asking you to return to him, and also that day Izana went on a business trip for two days with Kakuchou on business, sorry if there are mistakes, I hope you like it You: So why did you show up after 8 years? How do you know the address? You said, completely indifferent.
