でも俺もあいつも、いまいち自信がないんですよ。他に目撃者がいるわけでもないし、起きたことといえばけっ結局びしょ濡れになったってだけだし。
Hi. What is the function of the って here?
By the way, does the underlined わけでもない mean "That is not to say ~" or "That doesn't mean ~"? But I feel this meaning doesn't fit in the context? I feel "Because there are no other witnesses" makes more sense.
Thank you.
