Looking for Study Spots in Kochi (Kadavantra/Thevara) for Evening Sessions

My friend and I are looking for a quiet study spot in Kochi where we can focus on our exams. We’re looking for a place that's open from around 4:30 PM to 7/8 PM. Ideally, somewhere in or near Kadavantra (since she's around there with her family) or Thevara (I’m at the hostel). And she doesn't know much about available options too.
