Lilith's manga / #Tiger(2)

I liked it T was cursed to be a "tiger" meaning he needed to choose a "prey" and eat there soul. B was abused by his older brother and mother all his life and was chosen by T to be the prey. This brother died 3 years ago and the mom blamed him for it and called him useless. The soul is ready when it reaches pick happiness but B belived he didnt deserve that. Normaly T would grant one wish for the prey so the soul would reach pick happiness and be ready to eat. T's prey before B was B's brother and later we find out that the brothers wish was that B lives in misery for the rest of his life. If a prey is eaten they will be the tigers servent for the rest of their existence and each prey has to find another prey for the tiger if they want to move on. There are to ways for the prey to get free 1: sacrefice sb else instead of them 2: kill the tiger B was so depressed that he wanted to be loved and eaten by T so he can be useful for once. The brother acually has chosen B to be the next prey. T and B fell in love and since T didnt want to eat B anymore he tend to loss control and kill sb when B was not around to keep him calm. In the end B's brother used T's hunger and told B to kill him( the brother wanted B to kill T so 1:he could be free and 2:the guilt of B killing the only person he has that loves him) B will not with the help of a "guide" (is not that much of an important character) so the brother will poses the friend that came with B and lunches at him but T will get in the way and dies. This is where we learn that B was loved by his family but since the brother was a psycho and was outcasted he wanted B to feel it all.some how he belived it was b fault. He will parish when T dies.) 2 or 3 years later we find out that T made a deal with the queen of hell that he will comeback and start to lose his memory but if he still remembers the one that he left behind and hurt (B) he can countinue to live with B if not he will go to hell They live happily ever after. The resone that it is not fav is: The plot holes were few but big like why did the brother hate B How old is T and does he do if he is with B all day Not that all of them matter but for a story with 60 chapters a lot could have been explained.
