Perception check fell short of noticing the do-me eyes? Or was it a low Persuasion roll to convey flirtatious intent? At a guess I would imagine Konsi has a high charisma score and clerics do get access to Persuasion as a proficiency. Then again I've had cleric characters with both of those things botch rolls that resulted in violence I was trying to avoid, so a failed flirtation isn't the worst outcome, even if it's frustrating.
