Horimiya (ホリミヤ) is a manga series by HERO with art by Hagiwara Daisuke.
Hori is your average teenage girl, and in fact one of the most popular girls in her class. She has a side she wants no one else to ever find about, the fact that outside of school, she acts like a plain housewife to help out her family and take care of her younger brother. Then there's her classmate Miyamura, your generic glasses-wearing boy in school and with his long hair and quiet personality, is considered to be quite creepy and is a relative loner. He too is a totally different person outside of school. When the two meet unexpectedly, they discover each others' secrets and develop an unexpected friendship.
This series is a comedic slice-of-life romance story that is utterly adorable and heart warming. Don't judge a book by it's cover and don't judge people based on appearances and first impressions!
Currently 6 chapters have been scanslated, but I have become aware that this was based on an original web series under the same name!
It also looks like there will be an anime OAV:
