But there's one other thing that's confusing. Why did he molest Yuuji? It's not like they've known each other. Kousuke for example became a ghost because he was constantly thinking of Yuuji and thus he's "haunting" him. But there's no explanation why Takumi haunted Yuuji, a stranger on the train. His first transformation into a ghost seemed to happen shortly after the accident..hm....maybe a near death experience?

I think your theory seems pretty plausible... The near-death experience might've triggered his weird ability... And combined with some pretty obvious feelings towards a certain guy, it all seems to make a little more sense. Anyhow, we'll probably get some sort of explanation in a chapter or two. (๑•ㅂ•)و✧

When he was in a coma for the 2 months, his soul roamed around all over the place and thus why he was on the train. Back in the earlier chapters, Akiyama told Yuuji he wanted to tease him because Yuuji looked at him thirstily(in this case Yuuji was thinking how Akiyama is more suited as his ideal type)
It seems like the megane-guy in the second story shares the same memories as the uke from the first story... They aren't the same person... They can't be - I really liked the first story and my reasons for liking it were ---- uhmmm, very RaTiOnAl and ScIenTiFiC, yup ( ̄∇ ̄") I'm not trash, pls, just 99%
