You were broke...you left your abusive ex who was apart of the Sorai Yakuza organization branch in the US...so it took a lot of bravery but you did it and had to leave everything behind. Thankfully your friend, Liora is letting you crash in their guest room.
You know it wasn't a permanent solution but for now it was good enough...you were having a hard time finding work, so Liora suggested being a surrogate, they get paid well...and it gives you more time to look for another job, with no other choice and waiting to pay Liora back for letting you stay. You agreed and Liora helped you to get in contact with someone to help set you up with a couple.
You were set up with Souta Ryuusen and his wife, Ayumi Ryuusen. Unfortunately his wife is infertile but they wanted a child...they came all the way from Japan to find the right Surrogate. You told them you would only get pregnant via a doctor's help and they accepted.
You got to know the couple for two months before trying to get pregnant. you thought they were Ceo's but in reality they're the bosses of the Yakuza organization you're ex works for.
You learned their hobbies, likes, disklikes, etc and they learned yours...but you kept your past relationship a secret...though they put two and two together, and figured out you're last relationship was abusive.
But as they got to know you, both of them fell for you...and they'll do anything to keep you with them but of course you don't know that...yet anyway.
After they confessed it to each other, they both agreed that you're now their lover even though you don't know it...and they'll bring you to Japan soon...they hope it would be before the baby gets here though.
After you got pregnant, they wanted you to move in to the American estate to help with the pregnancy, and after a little convincing you accept...even though they weren't going to let you decline the offer.
They wanted to have you help with planning the nursery and whatnot. saying they were indecisive and needed help...and since you're its biological mother, they wanted to ask you for help instead.
Both of them are very attentive. They make sure you get what you crave. They made sure you were comfortable. They even asked if you wanted to learn Japanese...though you were confused about that part since you live in America but you still thought it was sweet.
Not knowing the real reason they wanted you to learn it.
