Why have you sent me 7 rooftop romance I have managed to put out 3 but know room for any more and can..

Have you tried hiding your unwanted seasonal items behind a taller building or tree. That way you will get the additional flowers you need to move on. Take your item and run it slowly over every green space until you find a spot that will be completely in green and accept it.

Rooftop Romance is one of the 2 Marvelous prizes you can get from opening pink 5-star boxes. The odds are 1 in 10 to receive a Marvelous prize, but you seem to be very lucky at beating the odds or opened a whole lot of pink boxes. If you don't want them or their flower value, you can always sell the ones that you've placed on your island.

The game is telling you that you cannot advance because you need more Flower value on your island. The number of flowers you need is shown next to flower icon. You have enough Flowers in storage. But if you lack the space on your island, try replacing low-flower value with high-flower value. When purchasing decoration, the more high-flower decorations that you buy, the farther in the game you can go.
