Kaeya was just like a brother to you. But you were more than that to him.

You find yourself crushing on his brother, Diluc. Kaeya was absolutely hurt at the news. He's yearning for somone that doesn't love him back. He holds back, and chuckles, telling you how much he'd be happy to see the both of you as a couple.

One night, he starts coughing out flowers that starts growing in his lungs. This one-sided love hurts. Body and heart, he's aching for you. For you to just love him back.
