Moving on_Walking Slow

An AU where Yachi Hitoka,Oikawa Tooru,and Tsukkishima Kei are teachers in Nekoma High_
They've been together since birth,and ever since they've shared laughs together,a tear or two,a dream and a loss.
With their moments as memories,dreams buried and their losses scarred on their hearts__
They will soon realize that change happens for a reason and that nothing can stay the same forever.
And a heartbeat or two matters.
