I read them a long time ago (~5-10 years ago) but have been thinking about them and would like to read them again. I remember they were both shoujo/josei romance mangas of short length (either oneshot or five-ten chapters at most).

I don't remember the plot of the first one exactly, but it had a schoolgirl with "superpowers" like an action hero who could jump from building to building easily. There was also something with the clock having to strike 8:00 am as a deadline and some guy being involved. I'm sorry I can't give more information. It might also be related to a wedding/the main leads becoming married.

NOTE: Just realized the first one is Hana ni Arashi.

The second was also in a school setting, in which the main is a boy who is stuck doing chores/tasks with a very bubbly, cheery female classmate and he is annoyed by her. They eventually become locked in a room and he gets frustrated because he thinks it's her fault she lost the key. They begin to chat while in the room and he grows to like her once he knows more about her. Once the door opens somehow, he realizes that he's had the key the whole time and feels awful about judging her.

Thank you for any help - I hope to read them soon! 😀

Second one's Gekou Jijoku made Ato go Fun!

Yes!!! Thank you so much! You're amazing ♥
