Cliché Storm: Lacking any deconstructive aspects that separated the characters from the standard personality types they were based off of, you're left with a fairly average paint-by-the-numbers shoujo romance.
Earworm: Opening theme Fure Fure Mirai, which is just as catchy as the memetic ending its name resembles.
In Chapter 10, Ryoko starts revealing embarrassing secrets about Yuki to Tsuruya, who does the same with Mikuru. Tsuruya then reveals that Mikuru has a star-shaped mole on her chest, which is something that Mikuru did not know before and is greatly embarrassed. Now, in Ryoko's case about catching Yuki checking her weight after a shower makes sense, since she's a close friend who frequently visits her, but, for Tsuruya to be the one to know about Mikuru's beauty mark is, while funny, a little strange, since it's not really explained how she knows...Not to mention that Mikuru looks seductive in that page.
When discussing Valentine's Day, Mikuru says she would be happy to get chocolate from Yuki if Yuki were male, and sheepishly admits that it came out like a confession.
Vanilla Protagonist: Since Kyon's perspective is absent from this iteration, the vast majority of his characterization goes along with it. Yuki's shyness may be endearing, but in the process of revamping her as the protagonist, she likewise loses a lot of distance and coolness that made her such an interesting character. In short, they become unremarkable shoujo leads.
