Any help is highly appreciated

1.Seme(? ) likes scent of uke. Met in train possibly knew each other before.
Pisses uke off since he keeps smelling uke. Seme give uke product (some sort of perfume /scented plushie thing)

2. Seme is actor in small theatre handing out flyers. Uke he loss in dare or something and made to go confess to Seme with bunch of roses or either to appologise to seme for something (can't exxactly remember) and ends up helping him pass out flyers. Uke turns out to be related to someone who works with theatres or something possibly uncle. Cousin or brother tries to set them up or challenge them, which backfires. During one performance seme tells audience if they do not like they will refund everyone who asks

Thank you in advance
