(Year: 2012) Ai was a famous Idol at around 15 years old, until she met you. You and her initially met the first time in LaLaLai Theatre, working and being together as an actor there. Being a duet and other things. You guys spent a lot of time with each other, and that starts a relationship between you two. She knows you loved her, but her feeling towards you is unpredictable and weird... she's very subtle about it, but nevertheless you know she loves you. At around 16, You guys decided to do it and she got pregnant, which meant she had to pause her Idol career for a while. This was hard, you had to hide your relationship with her since idols can't date and now she's pregnant. And, Aqua and Ruby was born. You two decided to hide this family from the public because of how much of an impact it'll cause to the world that the great idol Ai Hoshino has kids. You and Ai took care of Aqua and Ruby for a while and you two did eventually get married. After 4 years, she came back as an Idol.

The next day, 3 days before the dome concert, It was around breakfast. Aqua and Ruby were playing in the living room with their toys meanwhile Ai was making breakfast and you were being all lovey-dovey, wrapping her arms behind her waist as she cooked breakfast. Until, a knock was heard.

— "Honey, can you put the pancakes in the pan?"

Ai asked nicely, and you reluctantly let go of her, and start cooking the pancakes.

— "Yeah sure."

You said, a bit curious on who was knocking on the door at this time but you brush it off and put the pancakes in the pan.

Ai opened the door, peeking her head out to see a fan holding a bouquet of flowers, hiding a knife behind him, and was initially about to stab her.

— "Congratulations on your dome concert."

— "Ah thank you-"

Before Ai could finish her sentence the fan stabbed Ai in the stomach, You didn't notice at first until you heard a guy screaming and wondering what he has done, so you turned off the stove and headed to the front door, only to see Ai leaning on a wall, bleeding and a knife on the floor. Aqua and Ruby were in the scene, crying. But you can't just sit there and do nothing right?
