This is probably the first anime I've ever rated a 1/10, only because I honestly question it's existence. See, there's bad anime out there with bad voice acting, bad plots, bad animation but at least they're so bad you can take some enjoyment out of it either respecting it as a period piece or just laughing at how bad it is. But Furueru Kuchibiru is so boring and not bad enough to laugh at. This anime has no redeeming qualities.
Story: A teacher is in love with a student, they have some dumbass disagreement and the teacher doesn't care if she leaves or goes but at
the same time is conflicted with his feelings for her. The entire anime is about the teacher becoming comfortable with his feelings for her and the student, who is above the age of consent, is finally able to have an actual relationship with the teacher. Every line, every moment, every sex scene feels so lifeless and bland I was starting to fall asleep
Art: It's okay by modern standards but some scenes looked really weird, especially the beginning part on the toilet. It's worse than flash animation. Not to say flash animation is bad, I actually love it a lot, but this just... looks abnormal. I can't quite put my finger on it. Some scenes are very out of place compared to the flow and speed of other scenes.
Sound: It's normal. Nothing to comment on this unless you want to count the boring pointless lines the characters say. It's a waste of breath.
Character: Absolute trash. The teacher almost has no soul. He has no defining personality traits besides he doesn't know how he feels about the relationship, accept he does know but pretends to not because he's a dumb anime character. I don't know what to call this trope or even if I described it correctly, but this is not how a normal person acts and thinks, or a bad anime character for that matter. Chris from Garzey's Wing had more of a personality than this blank slate self insert robot.
The girl just wants to bone and be loved by him, that is her entire purpose in life. She's pretty boring herself.
Enjoyment: Zero. I couldn't even get a half chub to this snorefest. The sex is SO BLAND. Even if you like plain ol' missionary lovey dovey sex this is bound to put you to sleep. No interesting positions, not even good sex dialogue . No amazing climaxes or money shots. You'll just have to watch it for yourself to see how unimaginative this is.
Overall: It's garbage. This anime didn't need to be made. I haven't read the manga but I doubt it's as bad as this abomination. At least if it was REALLY bad I could laugh at some parts but with this I was neither laughing or aroused. Anime like this serve no purpose. It did not need to exist and I doubt it made any money. Skip this one, this is the first time I've actually wanted my wasted time back. Usually I think that "oh well this anime was bad but im glad I watched it to satiate my curiosity" I did not have that feeling with this one.
Gag me with a spoon.
