When will it get to his annoyingly thick skull that he's already trusted by his party? It was kinda cringy for him to insist on living alone because he's somehow a threat to three girls who already know and trust him. They made a good point on how they already slept in close proximity when camping outdoors. Thank goodness he folded and agreed into cohabitation.
And locks are supposed to be standard features of any door anyway... this ain't Japan yo.
