Haruna is late to her own wedding – she doesn’t want to get married, she just wants to keep running an onsen with her sisters – but she’s stuck in an elevator with Sentarou, the man charged with getting her to sign the marriage certificate. When they’re finally rescued they’re found in a compromising position that Haruna uses to her advantage to get out of her wedding and rope Sentarou into posing as her fiancée. Sentarou is now out of a job, so where can he go? How about the same onsen?
