Did you know that it is hot pepper, not bell pepper?
Based on the distinction described here https://www.helpfulgardener.com/forum/vi ... 81&t=70079
and the general leaf conformation, I think we can say that it is a hot pepper.
But there are approximately a million varieties of hot peppers, with very little or nothing to distinguish the plants from each other. When it fruits, that will at least narrow the possibilities down a bit. But yes, it will not fruit without LOTS of light, difficult to provide indoors.
