Similar to Nisekoi (especially with the pet term "honey" and such), but different in that there's a third wheel now steadfastedly determined to make sure the official couple doesn't happen.
I wonder how much better Nisekoi could have been if Onodera had been that assertive.
Well, then again, I forgot about Tachibana, who actually was assertive, but she seemed more like a nuisance than anything else. I never was very fond of that character. (lol)
