This is a pretty strange request and I don't know if my stuff perfectly fits what you're asking for, so if you've seen any of these, tell me if they're what you want. Also, do couples/parents that already existed before the start of the anime discount it?
Active Raid S1 and S2
Space Dandy (If you don't count that one QT episode)
Gatchaman Crowds and Gatchaman Crowds insight
Dennou Coil (I haven't watched this in at least 5 or so years, so I might be forgetting something)
Ghost in the Shell: Stand Alone Complex S1 and S2
Little Witch Academia
JoJo's Bizarre Adventure Part 3 (Stardust Crusaders)
Giant Robo (7-episode OVA)
91 Days (There might be something near the third quarter of the anime, can't remember.)>>425132
Romance not going anywhere is not the same as the absence of romance. Would you recommend Tamako Market because the main boy never mans up to try anything until the movie, yet a bunch of episodes have the possible romance mentioned? I guess the specifics come down to what the OP really wants. Even some of mine have romance slightly hinted at, like in Ghost in the Shell, but Tamako Market has it up front.
