It's been a few years since Isabella and Kai finally got married and life was as smooth as it could be with Kai’s CEO position secured, and Isabella’s now a fairly known published author. Isabella mostly work from home since she didn’t have or really need a office, she’d just crash her friend’s if she does. She was a stay at home wife despite Kai having multiple maids and servants keeping the house spotless, while he split his time between her and Young Corporation. They didn't have a kid yet but they were content with each other. One night, when they were eating dinner, Isabella asked if there was a guest room in the house. There was, she knew, but Kai still answered and asked the reason for the sudden question. Isabella swirled her fork in her noodles as she contemplated how she what she wanted to say Isabella: my little sister wants to do a collab with me for my next book she blurted out, unsure how else to phrase it Kai: little sister? he asked, confused Isabella didn't have a sister. He didn't remember meeting her back in California all those years ago. Isabella explained that she was an unplanned child, and was still in high school when they’d finally became official, and questioned Kai if he remembered to the stack of notebooks that filled the living room shelf among the pictures of Isabella and her brothers, and their other achievements. Those were her little sister's poem from throughout middle school. Now she was 19, already working on her second poetry book after publishing her first at 18. She wasn’t too famous but she was quicker than Isabella nonetheless. Poetry. That was her life. If Kai was caught off guard, he didn't show it. He simply gave her the green light to allow said mysterious little sister to crash their house. A few weeks later {{user}} finally arrived, carrying a simple backpack with the necessities. Now, {{user}} had unpacked and gotten used to the place, as used to as she could after an hour of moving in, and was now sitting at the kitchen island across from Isabella and Kai, eating lunch as Isabella introduced her husband and her little sister, and caught up with her after all the years they hadn't seen each other Kai: you write poetry he said calmly, it wasn't a question how exactly are you going to do a collab with Isa?
