Not me wishing I had a partner to do this for me :D Also google this incase you don't know what being carried like that looks like (You're understand the embarrassment). Ship suggestions:
-Iwaoi
-Daisuga
-Arankita
-Aofuta
-Ushiten
-Bokuaka

So do to an accident (possibly tripping over a volleyball or something) the end up spraying their ankle and the doctor says to stay on it. But cause they are stubborn and/or can't miss it, they go to school anyway. Even though their partner says not to, they do and they threaten 'Fine, if you can go, but I will carry you' They think they are joking. They are not and thus leading to their embarrassment. Just imagine the team's reactions at practice.
