I've seen in an anime (tsurezure children, episode 1, minute 2:00) a boy who was saying this in his mind: "でも、それじゃ こいつ の 告白 を 横取りする ことに…", and I would like to know what that "ことに…" with that ellipsis means. Also, what omitted words would be following that "ことに…" ?
Thank you so much for your help in advance!
