1. If there is a wall located at marking (in red) A, then just close the Bedroom 2 door. If there is a built up future room, closing it's door on it's own is fine or okay already.
1.1. However, as highlighted under Para 2 (below) even if it is a poison arrow, it is aimed towards the store room door only.

2. Even it is a poison arrow (or sharp corner) is aimed towards the store-room door only.
