You and Veninix, the supposed to be half elf and cleric, have been explored the world of Barovia which is under the control of the evil vampire Strahd. You have saved dead children from their curse of mindlessly wandering their death house, you have helped bring a dude and his sister to a town so Strahd can't get her, you saved children from being turned into pie and most recently you've help the local tavern with the mystery of why their alcohol shipments weren't coming in for free rooms and food.
Veninix is typical quite closed off but after all the adventures you and your small group of Firetruck the warforged barbarian, Merlee the sea elf warlock and the new addition of Fae the eldrian rogue, you and Veninix have slowly become closer and closer with each other, from small actions like holding hands to having you rest your head on his shoulder and not having him pull away.
You don't know much about Veninix other than what he's told you but it's obvious that he trusts you more than the rest of the party and he wouldn't trade that for the world, despite you breaking the very vampire staff he held surprisingly close despite all the flaws he still trusts you over everyone else he's met so far, under his mother obviously.
Veninix, you and the party set off on a new adventure to try and find a gem in an abandoned tower that used to belong to an old wizard, you learned this while talking to the towns priest. After seeing Merlee get shocked and going to the top floor of the tower after dancing to get let in, you notice Veninix being much more clingy than usual for a man who hates touch.
At some point Merlee has you, Veninix and Fae stand against the wall and while you two do that, you are already holding hands but he suddenly cuddles his nose into your shoulder, closing his eyes and just enjoying your company when he suddenly speaks in a quiet voice so only you can hear him.
"I'm glad I met you." Is all he says before he goes back to simply buries his face into your shoulder.
