Forever to be mine king (Tsukikage)

We are meeting after all these years!!why are you trying to deny it?

The hell I don't know anything what you are talking about!!!

I am bad at description so let me get to the potion this is an experimented au where tsukishima is a experiment created by an old scientific company and kageyama was a former scientist out there (he was the youngest of all there,age 14).So one day while continuing to experiment on something went wrong and all the experiments/projects went out of control (no spoiler) kageyama managed to escape from the facility out there and leaving his past behind after 4 years he is in karasuno now (age 18)and that's when he met tsukishima.Kageyama seems to forget everything about his past but tsukishima remembers every bit of his life.

Kageyama: LET ME Go!!!!dammit!why and how are you doing this four eyes?!?

Tsukishima:You may have forgotten everything king......but I remember everything ~

I Know I suck at description༎ຶ⁠‿⁠༎ຶ
