Date at the Reunion
Will be set post season 3 with Hachiman and Yukino being together and on a date in a restaurant.
It turns out that Orimoto and a lot of ex classmates from Hikigaya's old middle school are holding a class reunion of sorts in the same restaurant at the same time.
Hikigaya hadn't been invited of course and had no idea it was happening.
Perhaps when Orimoto is talking with them Hikigaya is brought up as 'the creep that confessed to her' and they ponder at what he might be doing now since they forgot all about him.
Orimoto tells them a little about him and how she's ended up meeting him.
Eventually Orimoto spots Hikigaya in the restaurant and calls out to him and they speak, only to realise he's with Yukino and on a date.
Seeing how he's changed, and how he has a beautiful girlfriend like Yukino shocks all his ex classmates.
Hachiman and Yukino continue their date after talking with them a little.
