This is the part two of miko amayo's Unaging Character thread. Both of us can't remember the title of the friggin' manga. Here's what amayo-san remembers:



Now this is what I remember:

The Main Character (not sure if girl or boy) enters a school or an old castle turn into school (not sure) and meets a mysterious black haired boy. They became somewhat friends, with the MC still wondering about the boy's real identity.

In later chapters/pages the MC gets hold of a faded photograph of three boys (or was that two boys and a girl?). One of the boys looks like the MC's friend, but with white hair. It was later revealed that the MC's friend uses dye to hide his white hair. The photograph was taken years before, (maybe when the school was newly built).

Back then, the boy and his friends were experimenting how to gain eternal life. The first vial was created but there was no test subject. The boy agreed to be the test subject because (I think) his girlfriend played some part in it. (The girlfriend would be his wife in the future, the one he caught cheating on him. ) Instead of eternal life, the boy gained eternal youth, and his hair turned white as a side-effect.

I think the boy's other friend (the one in the picture) is the current principal in the MC's school. They're still experimenting to find a cure or to perfect the serum, and the school is still shrouded with mystery.

It kinda feel like one of Count Cain's cases, don't you think? But I'm not sure.

That isn't just like Count Cain, it is. The Cain Saga Volume 1: "The Boys who Stopped Time," the third story in the volume. It's an unrelated oneshot that was included in the volume. I recognized it immediately, and even pulled out my hard copies to confirm.

Gosh, I knew it!

The first time I read amayo-san's post I was thinking of cravats and frills. But GodChild's plot seems different and I can't see this as a side-story. I was ready to go and re-read it when no one posted.

Either way, thanks for your help!
You just save me from a lot of work...
