Please Put Them On, Takamine-San, Vol. 10 Volume 10

The school trip is fast approaching, and Takamine's more than a little worried Shirota won't be able to keep up with everyone else, so there's only one thing to do-go on a trial run! Eri and Rurika are along for the ride too, and after Shirota and Eri head out to buy supplies, Rurika finds herself alone with Takamine, who she can't help feeling awkward around. What on earth could have happened between these two, and why does only Rurika seem fazed by it...?
