[Shiga Sawori] Nayameru Hime to Mayoeru Ouji [Shoujo Addiction]

A childhood marriage promise once bound Hukino to Ryousuke, the older boy she swore to stay beside forever, but word that he's now meeting arranged bridal candidates leaves her heart tangled in doubt over whether their vow was ever real. Meanwhile, a friend's generous resort voucher sends Ayana off on a getaway with Sawamura, only for the pair to discover their booking covers a single double bed. Tender confessions, lingering first loves, and the charged hush of a shared room carry these intertwined romances about promises made young and feelings that refuse to stay childish.
