D': That took a wild turnnn; quite bloody. Yet it is definitely an artistic choice rather than purely shock factor.
So many symbolss, what do they stand for... Toxic love? Attachment?
Or, a type of gnawing jealousy that grows after an unrealistically perfect person proclaims their love for you? Once they receive what they need, like a shelter to grow their wings in, will they fly away? Will that love fade? Might as well just take her wings away before they mature, so she has no choice but to stay. Yet, both will suffer for this.
Will wait for the epilogue.
