If we're talking about girls belonging to the main harem, normally one of the girls that has a crush on one of the main ones (or shows a lot of yuri openings) so it starts as a rivalry with the protagonist but somehow ends attracted to him. It's normally one-sided, but you can find it on old series such as Bakemonogatari, Haganai (outside the main harem there's also a yuri harem), Oreigaru or Nisekoi, to name some but few. If we're talking about a romcom but yuri, then of course you're going to see plenty, the most prominent is Which One Is Love? And finally, if we point towards comedy series, then you have both Temple and Grand Blue (same artist but different author, the latter is the best), Yuna and the Haunted Hotsprings also has yuri vibes from some characters, series with gyarus included sometimes are bi (not the case of Dress-up Darling, but that gyaru loses control with the legal loli), but it's hard trying to recall all of them. Outside romcom it's easier to find side yuri couples, under Seinen and Josei tags. But if you want to see yuri... just get out of straight romcoms and read actual yuri, it's for the best.
