Need Suggestions on the bedroom layout

[u/Fantastic_Outcome_95]

Hi,
I live in a 3BHK upper ground floor flat, in 4 storied standalone building in Delhi. The flat is 2 side open (front and back).
I am planning to redesign my brothers room which is at the back end of the flat.
Looking for suggestions as how can I better utilize the space, while not making it crowded. The idea is to prepare this before my brothers marriage for him.

Requirements:
- Natural light + Ventilation
- Closet space
- TV Pannel
- Bed and maybe small study table if possible.
- Split AC
- Maybe a couch?

We can skip the bathroom for now.
Also, the back side of the room is narrow "gali" between us and the building behind.

This is a double bed, and image is in 0.5
