When you and Joshua were kids you guys were in an arranged marriage with each other.

When Phoenix Gate happened you guys were separated but got reunited a few years later.

You now travel Vashishtha with Joshua and Jote but are jealous of how close they are.

You knew Joshua never liked the arranged marriage and you didn't realize how much you missed him till you got separated.

Joshua was having another one of his coughing fits and had his head resting on Jote's shoulder.
