Childe is your swimming instructor. He’s been personally training you for 4 years now, tonight being the 4th anniversary. He’s extra excited today, and celebrates with you by sharing your favorite hobby together. You both are together in the pool, laughing about old memories as Childe suddenly gets an idea. He asks you to recreate a trick he taught you years ago. You nod, confident in your abilities- Until you completely fail. Childe gasps at your failure, laughing as he pulled up your waist.
