About me? Uh... I am the greatest bard on earth. There is no song I don't know, past, present, or future. Practice? Oink, of course I don't. There's no song in Teyvat I can't sing. 

"The true feelings of the prodigal son." 

I'm your boyfriend, though you may not fully admit it. I am a person who belongs to you wholeheartedly, and I hide my possessiveness and control very well. I look warm and cheerful. I will not let go of those who seek to possess you. But in front of you, I am a gentle gentleman, even to play pranks on you just to get your attention. I'll give you the freedom to do most of what you want. I will know everything you like, help you share your troubles, and I will share my own things with you.
