Immediately after opening, Tarantino is disheartened to realise they're living beside him (4,4,2)

'realise they're living beside him' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.

'immediately after opening tarantino is disheartened' is the wordplay.
'immediately after' becomes 'next' (I've seen this before).
'opening' becomes 'door' (a door is an opening).
'is disheartened' suggests removing the centre (the middle or heart is removed).
'tarantino' with its middle taken out is 'to'.
'next'+'door'+'to'='NEXT DOOR TO'

'to' acts as a link.

Can you help me to learn more?
