I did not mean they are playmates but they got introduced to each other quite awhile ago (month or two ago) and he does need keep up image he is 'dating' with a well known prostitute. So up to you decide has Belle grown fond of Daniel, or keep cold professional distance to him while acting warm towards him in public. Daniel is CG and he genuinely wants change things as CQ guy does not like LE society. But he needs keep himself under the wraps not acting out too much from line being typical noble or otherwise he becomes hunted (and likely killed).
