In all honesty, I'm not surprised that Jaeha committed suicide at the end of the original timeline. Not only was he part of the reason that his friends/teammates got trapped and killed in that tomb (even if it was unintentional), but any chance of at least one of them actually escaping was destroyed when he lost his temper and didn't repair their relics. It's sad but if I was put into that situation......I would've done the same thing
