「」。
"This looks really interesting," Hiroshi says.
Literal
"This [topic-は] very interesting-seems [feeling-ね]" [quotative-と] Hiroshi [subject-が] says [polite-ます].
~そう attached to an adjective stem means 'looks/seems X based on appearance' — 面白い → 面白そう. Note that this is the 'appearance-そう' (not the hearsay ~そうだ attached to full forms). The sentence-final ね invites agreement from the listener. ひろし is written in hiragana here — a stylistic choice, possibly suggesting the person is a child or giving a softer feel.
