Can you romance Kelly Chambers and Samantha in Mass Effect 3 after having had dinner with Kelly and she fed my fish?

In Mass Effect 3, you can romance Kelly Chambers, but if you've already had dinner with her and she fed your fish, it indicates a previous romantic interest. However, you cannot romance both Kelly and Samantha simultaneously, as the game has specific romance paths. If you pursue Samantha's romance, it will prevent a romantic relationship with Kelly from developing further. Choose your romantic interests wisely, as they can affect your relationships and interactions throughout the game.
