It's mild,at least this is what I can deduce from "reading" the raws.And I guess if it has the romance tag then it's gotta have some,like it or not. ╮( ̄▽ ̄)╭but than again it's rare to find mangas with the EXACT genres that you want without anything that you dislike.
i hope this doesn't focus to much on romance because I'm only reading this for the plot
