Enemies..?

Nekoma makes it to the semi-finals where they have to be face against Nohebi.
Yaku hurts his foot/ankle and has to be switched, Shibayama the 1st year libero comes in, under pressure at the start he gets calmer each time a point is scored for their team.
Yuki makes eye contact with Kuguri just as kuguri is going to spike, after the match they bump into the each other after apologising they went to their teams.
That night they both start thinking of when they'd see each other again...
