The sentence is missing a subject. Could that be the problem? Otherwise, puis and ensuite should both work here.

Hi Kaimaru,

The two adverbs are indeed very similar, but I sense a nuance.

Do you want to express "then" -- ensuite or "and then" -- puis?

I would expect to find "ensuite" used in a situation of a series of expected events.

However "puis" simply expresses the next event but not necessarily in an expected series of events.

Let's see what other contributors think.

Bonne journée
