Cute style (potential yuri? tho i can totally imagine some shoujo fantasy where some doll comes to life as a love story too XD)
I can understand renting out a private karaoke room but soundproof walls and cameras aside surely there'd be something at the front desk that's like "Song is playing in room 3 for 2 mins" to let ppl know the timing of such
I feel like ppl would judge bringing a doll even if you were in full lolita garb yourself, but personally i'd worry even if my purpose was to take a pic at a trendy cafe that i'd end up losing/forgetting it XD
@Pinyapple can you add the summary, please?
