Shinryaku Ika Musume (aka Squid Girl) is a comedic manga turned anime by Masahiro Anbe about a girl from the ocean who attempts to get revenge on humanity (by herself) but ends up working at a beach house instead.
In episode 2, she meets the hunky lifeguard of this post, Goro Arashiyama, who may have a crush on her. I looked at the original manga for comparison and found out that Goro is beefier in the anime than in the manga.
Screencaps featuring Goro (not taken by me) are below.
