Help me!?

Help me find bl manga/manhwa/manhua title I read a few years ago. I don't know if they are from the same manga/manhwa/manhua or not. And I only remember a little.

1. Seme and uke is a celebrity, they are in variety show. In the variety show the divided into different team to do some mission. Rather than doing his own mission, the seme choose to help the uke doing his mission.

2. Seme and uke know each other for long but one day they lost contact with each other. A few years later they meet again in another city they are from at night.

3. Seme and uke is a celebrity doing a variety show in a theme park. There's rollercoaster and the uke force himself to ride the rollercoaster even tough he is scared of rollercoaster, and he feel sick after riding it.

It's the only thing i remember I hope i could find the title of these manhwa so i can read them again.

Thank you in advance.
