I am jealous. Back in like early HS, I had a girl who behaved a bit similar towards me. Hit my shoulders/back when saying "hi", pestering me quite often, drinking out or biting off from my stuff only. Once she even gone on all fours on my desk with her v-neck in her shirt being basically on my eyes level - I could like see he pants/belly button/stuff cause her tits created nice "see through" windows with that v-neck. Part when she mistakenly believed I have a crush on a different girl, who she had a bi/lesbo crush on too, she kinda stopped her pursue after me and started pushing us two together.
Issue was that she had huge tits like the teacher here, and kinda-ish short legs with massive calves - both things basically completely removing her from the list of girls I was interested in cause of my leg fetish and petanko enjoyer-ism

- which makes me jealous of this MC who has a cute petanko, with nice legs/body pinning after him madly.
Mind you I kinda see the similarity here - he pins after older big booba girl, but is pestered by cute pentako same age girl. I was pestered by big booba girl, but was after a small breasted cutie. In both cases we were pinned after by girls we didn't like and pinned after girls who didn't care about us

. And if the girl in my case kept at her fight towards me, we would probably both end up with them - like MC will end up with the girlie in this manga.
