It's a bit similar to Lovely Complex, Tall girl ╮( ̄▽ ̄)╭,
Small guy(๑•ㅂ•)و✧. Anyways, she pretty much always covers up her pretty face. The small guy is blunt, smart and attractive. I read this once, but i completely forgot the title. It's funny, and has romance in it. I think. But yeah, hope someone could help me out (●'◡'●)ノ Thanks.
i've read plenty of tall girls in shoujo but think http://www.mangago.zone/read-manga/haru_x_kiyo/ matches your description the most.
The art is really eye-catching, the mc is a long black haired girl (eldest w/ male siblings) and she was on her way to school, she sees a boy (blondie i think) who seems to need help with something, they end up riding on her bike together. She's his senpai and he comes to her class and hang out, boy seems to hold a crush towards her.
