Add Aketsu and Yancha and that's pretty much it. I hate the needless drama it brings. I want Romance Comedy in my Romance Comedy and having multiple love interests isn't easy to write, and it almost always comes down to the "Second Girl" being more aggressive and forcing the "Main Girl" to step up. I blame Komi San for destroying any enjoyment I had of this trope by having the famous Fake Out "Second Girl Wins" then a week later taking it all back. I just got sick of having issue after issue dedicated to nothing but fluff, it's romantic filler before the "Main" couple actually has progress.
And I'm not talking about Harem Manga's, that's important to note, but Romance Comedies with a single focal point(usually with the girls name in the freaking title). Then around issue 10-20 the author or editor has to jam in the "Second Girl" and all the fun charming one on one moments fade away. It happens every... single... time... The exceptions are not the rule.
Even stuff like Boku teased the blonde for a couple of arcs but made her a good friend/wingman. But Nagatoro has TWO annoying second girls with the Student Body President and her sister who love to strip naked for no reason. And don't get me started on "Broken Childhood friend" and needless drama, it went Gal Cleaning on us and added a r*pe subplot which ruined the series for me. I still think about that cup shaking in her hands almost a month later, hate it.
