With every chapter Kariu becomes more annoying and less realistic. At this point she is just retarded social tsundere with mental state of 6 years old. Is author purposely trying to make her unbearable or what? If this supposed to be dramatic scene then it's total failure. The only emotion this chapter evokes is irritation.
I don't get it, why mangakas keep doing this shit even when they are capable of write without these forced dramas.
