I read it a couple days ago, it was OK, but I found it a tad boring. Maybe it's cause the main character is so plain and all he does is ride his motorcycle and run into people. I agree with you that I have no idea what's going on. Anyways it should be good until it's end at 5 volumes. Apparently the mangaka or whatever you would call a korean manhwa author, is also the artist of Until Death Do Us Part.
