One Day, My Best Friend Suddenly Turned Into a Sickly Girl From the TS

It had been a while since a mysterious disease was discovered in modern times.

TS disease is a condition that only affects males and turns them into females in an instant once it manifests.

My best friend, with whom I had always been close, unfortunately, contracted this TS disease.

Changing from male to female, naturally, many things began to change.

But I couldn’t abandon him… no, her.

Even if her appearance changed and she became a woman, she was still my precious best friend.

That was something I believed would never change, no matter what happened.
