That is the perfect set up for a sitcom, yes.

Though I think it could be interesting for Hoshikyo to get to know him a bit too. Since Shikamaru is a bit more involved with Luceti-plot type things, which Hoshikyo is more likely to involve herself with, it'd be a bit harder for her to make an effort to avoid him as one of the other.

Plus it opens the possibility for terrible/awkward reveals in the future, which are always fun. :'D
