It was so difficult for them already don't make it any more tough ah!!!!
It's like vampire stories just needed to be triggered to start journey as sucking blood. Btw she was suicidal from the first it was not the younger brothers fault cause he never forced except manipulation I guess . He manipulated his elder brother Sai to be a blood bank for him ...and at the last panel the younger one made the elder one triggered I guess so. Btw except the younger bro jerking off to his elder brothers there's no romantic love between them .
He doesn't care about him ..... (⊙…⊙ ),there's no L O V E
yup he doesn't care about him at all rn but later is a whole other story
So later on does he care ?

Spoilers aren't needed but thanks for assuring that atleast Zhenya will care for him later on ..
