There's something nice where the dialogue is calling out all the manga clichés, and the characters keep subverting them. Like "Did you go in her room? Did something naughty happen?" No, he just cleaned and made hamburg steak and was polite. Also "You should find a fake boyfriend, and over time it will become real! Just like a manga!" No, he was just a nice boy and had attractive skills and didn't slobber all over her. Feelings caught already!
The most disappointing thing would be if they actually do the ecchi tropes.
