I would like to request one, please, with Sadie Sink.
The reader is a world-famous singer whose first acting role is in the fourth season of Stranger Things. There he meets Sadie, and although their characters aren't love interests (nor will they ever be), they have great chemistry, as do they as people (demonstrated in behind-the-scenes photos/videos, interviews they do to promote the season, and at the premiere, where they're always shown together). Throughout the filming of the season, they end up falling in love. After the season premieres and each actor is focused on their own personal projects until they're notified about the fifth season, Sadie and the reader remain inseparable. They never stop seeing each other, and that's when they confess their feelings and have their first kiss, their first dates, etc. The reader also starts going vegan for Sadie. And some time later, they move in together, since they've technically been living together for the past few months.
Although Sadie has always valued her private life with her fans, the reader is quite the opposite, always sharing his life with them and constantly interacting with them. So, with Sadie's permission, he constantly shares parts of his love life and home life with Sadie (including veganism, which many fans jokingly started calling "the true test of love," although the reader had no trouble going vegan; Sadie made it very easy). The fans were excited, but not surprised (since they all suspected it), to learn that they are in a relationship.
