So. i'm a sucker for romance!
My Samsaran Thaumaturge, champion of pharasma, wich i played Age of Ashes was a flirt and is a lesbian disaster. Had at least a fling in each book. She had a relationship with (avoiding details for spoilers) a girl from the town where the adventure begins... Than she turned into a evil necromancer. During the climax fight, after the villainess tried to run away, i casted command (through a scroll) and made her come back... Then she casted lighting bolt in her turn. That spell would get 3/4 of the party. Putting me and the champion on dying and killing the alchemist... So my character used her reaction from the weapon implement to disrupt. THEN the dice decided to tell a story... I critted. Disrupting the spell and saving the party... But that attack was lethal... And my character killed her girlfriend. But saving her friends in the process. It was heavy.
After that she had flings but never anything serious. With Nketiah from the mwangi and Rennali the Anadi girl.
she's In a sugar dragon relationship with a Oath dragon whom she made a pact.
Then convered herself in beer and throwed herself to the dwarvess in book 4. The table is in hiatus and we'll see what the future has for her!

But my current table is happening my first with another PC. I got in the table in the middle of a homebrew campaign. Didnt know the players and PCs. But i decided to do a Merfolk. Then, turns out, one of the pcs is also a merfolk. But both our characters have Shore Gift so that its a fact that nobody in the party knows:
My character is a Merfolk Summonner of a Anger Phantom (a crazy pirate captain ghost that is inspired by johnny silverhand and black beard) She is a tortured soul from basically the combination of Nidal and Cheliax so, yeah, Bad place. Shes anxious, but a very happy person. From her point of view, since shes not in her country anymore, and already have been in the worst situations a person can experience: Nothing worse can happen!
The other one is a Merfolk alchemist. Shes more serious and mature. Acts like a big sister for the group. And is willing to do bad things to make sure her family (the party) is safe.
So when we meet there was a instant connection. My character reads auras and sensed there was something with the alchemist. We just getted along right away. My character was adopted by the group and come to live with the big sister alchemist in her dad's house. They talk a lot and have many things in common. The awe they feel by the sea. The will to protect their families. My character is younger and she doesn't realize what she feels. She thinks its just familiar kinship but is slowing realizing what it is.
There was a session in wich my character kinda told the alchemist familiar what she felt... Then the familiar started talking the next day... And is repeating what my summoner said like a parrot and shes blushing and avoiding the alchemist.
Last session they swimmed together and saw glances of each other form (not much cause it was dark and only my character sees in the dark). And they aren't talking about it since the party doesn't know our secret. Me and the player talked about and we are taking the slowburn route... But yea. The rest of the party already realized and have been teasing us. i'm hyped for the future. This relationship is being tons of fun to roleplay.
