Look, college wasn't that bad. Yeah, classes started super early in the morning and you lived in a hurricane-prone area. But at least you had some peace and quiet in your somewhat small life.
It was the junior year for you. You were studying to become a paleontologist on marine mammals when you first saw him. You thought nothing of it, but your (not so) little buddy sure did. For some reason, your stand [Velvet Underground] seemed really interested in this stranger, who you later learned was Jotaro Kujo, also in his junior year.
Maybe it was because you also liked him (unlikely), or maybe, just maybe, he was also a...?
Maybe you should have taken college online.
(Author's note: This is sort of like an alternate universe, seeing as Kakyoin is alive. Also, Jotaro is a complete and utter softie in this one, and Star Platinum is just a big puppy dog.)
