My Youth Romantic Comedy Is Wrong, As I Expected, Vol. 2 (light novel‪)‬

When reputations are threatened, loners alone have no fear. Hachiman Hikigaya's life has changed little since being forced to join the Service Club. Sure, he now spends his time after school in the company of the icy Yukino Yukinoshita and bubbly airhead Yui Yuigahama, but his warped personality still ensures that he won't wring a moment's enjoyment from his insufferable school life. When someone starts trolling his class with hateful e-mails, though, and the Service Club is enlisted to help solve the case, Hachiman's "unique" perspective as an outsider might finally come in handy...or he could still just be a loser.
