Even the strongest strings can be snapped by betrayal.

Brothers who seems so inseparable can be torn through time.

And all it took was oblivion to interlace it once more.

Estarossa losses his memories on Meliodas' betrayal. Torn by guilt and the desire of wanting what they lost back, the blonde took him in.

Everything seems normal, they were close again, happy again and together again however things were not that easy...

Set after Ban returned from the purgatory, and the war still goes on. Merlin somehow turning Estarossa back as a child and yeah.
