[OP08-106_p1] - Nami (Two Legends: Parallel)

My opponent took damage during the same turn in which I used this [Activate: Main] effect, and their Life card was "OP08- 106 Nami". What happens to the "[Trigger] Activate this card's [On Play] effect." on "OP08-106 Nami" in this case?

In this case, your opponent can choose to activate the [Trigger] effect on "OP08-106 Nami", but because [On Play] effects are negated, nothing will happen and [OP08-106 Nami] will be trashed.
