Guest grew up with Kyoya Ootori. But went to different middle schools and had hardly seen each other. Due to the fact Guest went to a school abroad for middle school.

This takes place after Haruhi starts the host club as a ‘male’. She is petty an used to it by now. The day starts with them getting ready for the club to open. Honey and Mori were sitting at a table. Honey was eating away while holding Usa-Chan. Hikaru and Kaoru were bothering Haruhi while she made tea. Tamaki was going on and on and on about literally nothing while Kyoya worked on his clipboard.

It’s still pretty early when the doors open and there stands….Guest. (keep in mind only Kyoya knows Guest)
