Finally! I get to write Corrin's!
Corrin: eh? Why?
Because CelestialStarlight is super excited for this! And I am too!
Corrin: I see, how long have you've been looking forward to this?
Ever since I planned it! Now shut it and let's get on with the story!

Note: I will address the female counterpart of Corrin as Kamui. I'm going for the brother and sister relation so Corrin and Kamui are siblings but Kamui is older.

You stared at the endless blues of the ocean. It somehow reminded you about Corrin the new smasher who joined a few months ago. You were close with Kamui-Corrin's older sister-and even closer with Corrin. The two of you sorta just click.
You were positive of your feelings for Corrin but was too shy to admit it. So now you just wait and wait until the days go by.
You continued to stare at the surf wash over your feet until your sunhat was caught by the sea wind and was thrown off your head. You quickly turned around to catch it but someone else had beaten you to it, a certain someone.
Corrin sent you a soft smile "I believe this is yours fair lady?" He handed you your hat back and you put it on. You blushed and murmured a thanks before going back into starting at the sea.
"It's beautiful isn't it?" Corrin asked, you nodded in reply and continued to stare at the surf. After a while of silence Corrin gently took your hand in his "there's something I want to show you" he paused "may I?" You blushed and nodded, allowing Corrin to take your eyes away from the crystal blue waters.
Corrin brought you to a rocky hill. It wasn't exactly a hill but a rock formation near the ocean, like a cliff side. You and Corrin slowly ascended the cliff, conveniently there were stairs and railings. You were marveled by the flowers that grew on each side of the railings, they were so vibrant and colorful. Finally you and Corrin reached the top. You gasped, on top was a huge white gazebo that overlooked the ocean. You grinned and ran over to the edge, letting go of Corrin's hand to marvel the view. Needless to say, Corrin was a bit disappointed-a lot actually. He had enjoyed the walk from the beach to your current location because you were holding his hand.
He joined you at the edge, you seemed to be enjoying yourself. The sea air was relaxing and salty, it was really stress relieving. The wind blew at your hair making it fly and Corrin got a whiff of your hair. It was a little weird but Corrin thought it smelled nice.
This time you were holding your hat since you didn't want it to fly away again. "The view is amazing" you said staring at the crystal clear waters "it is" Corrin replied feeling a bit nervous about what he was going to do.
He took your hands in his and blushed "your the most beautiful and kind person I met in my life, your quietness is your charm point and you charmed me with your bright (e/c) eyes. I love you will you marry me?"
The sudden burst of compliments brought you back to reality, you blushed and murmured.
"Um, Corrin...we aren't even dating"
He smiled "well then" he replied "will you become my girlfriend?" He asked gripping your hands gently. You smiled and nodded "I would love to" Corrin grinned at your reply and spun you around-which made your sun hat fly off down the stairs "Corrin my hat!" You exclaimed softly turning to the direction of your sunhat "don't worry (y/n) I got it" Corrin set you down and went to retrieve your hat but it kept flying away from him in the process. You giggled, now you know why Corrin reminded you of the sea.

Yay! This one came out great! I'm pretty sure you guys know Corrin's connection to water so I won't need to explain. I hope you guys liked the scenario. I come from the Philippines which is known for their amazing beaches and great views so I know what I'm doing here and because of that I developed a love for water and the sea air and yes I altered the preview, I wanted it more fitting into the scenario.
