I don't read things by this guy girl because they always end up like a K-Drama. If you value your time, and have too little energy to see lovable characters get hurt, then give this a pass.
Pre-emptive tag warning: Trauma, tragedy, cheating, sexual violence, humiliation, melodrama, and more. Guarantee you that you'll see every negative character introduced in chapter one squeezed out like a toothpaste tube for the drama.
Expected tags which will not appear: Slice of Life, Easy Reading, Heartwarming.
Do yourself the favor, if you're looking for something to make you feel happy after work or school, ignore this and the threads about it for two-four years and then return to make your decision.
The last part I want to mention is that Kei is well known for using sexual violence and netorare as VERY EXTENDED (talking 40-50 chapters) plot contrivances which border on unhinged, compulsive, and deliberate. This is not novel, nor is it tasteful story telling.
If you like any character in this manga they will get hurt and the main character will let them and probably be part of it.
If you do enjoy the warning tags, happy reading comrade. I don't share your taste, but I respect you.
