I hate Dupes because the only Dupes i get are from Girls i don't want^^

I want Justicia, Lantana and Evening Primrose badly for a specific Team but i am stuck with my Harem for a long time now.

I have evolved Bipinna Cosmos yesterday... I hope she is satisfied now and she leaves me alone
(Btw. i had 4 Dupes from her so far and she didn't get her Skill Level Up twice)

Don't get me wrong i would love Dupes from Orchid, Camellia, Japanese Iris etc. but if you get Dupes from Girls you don't like it's a kick in the guts...
