Dengeki Daisy, Sora Log Recommendations
The both give you a similar feeling. The main guy is a anti social boy and the main girl is a clumsy kind hearted girl that had/has an overprotective brother. A secret in the past connects the protagonists.
This kept reminding me of the other. They both are really funny and have those super cute aw moments(: If you liked this one, you'll definitely like the other.
