I thought that the light novels might add quite a lot, but I always get surprised by how much detail a manga/manhua can pack in. There wasn't much added by reading the original light novel here, but I did enjoy it, and it does give a bit of an extra insight into Seiichirou's thoughts at some points.
In this volume, Aresh's controllingness is... there, but not so bad yet. We'll see I guess. I hear they eventually fight about it.
