She pushed him with bunch of flowers ?

I don't know how the flowers ended up in the water, but they were just floating there. For all I know it could be a table decoration from a restaurant on the pier which had been accidentally knocked in the water, but it would be much more interesting and dramatic if it was some couple who got into a fight.

It was just a kiss,
so flowrers felt down

Yeah, maybe the flowers fell in the water while they were kissing. Nice and romantic!
