This is a set of volumes 1-4 (all currently released volumes) of "Utsukushii Kare" by Yū Nagira and Jin Kitano. This is a comic adaptation of the very popular series that has also been made into a drama and a movie. The long-awaited 5th novel is coming out soon. I have read it once. Please note that the packaging will be simple, with only waterproof measures taken.
