Having lost his powers, Shirogane now has a problem he has to deal with, and a proposition for Suzu and Matsuri.
Because he knows doing that wouldn't 
repair his friendship with you.
Il sait que s’il fait ça,
ça ne vous réconciliera pas.
Sa che, se lo facesse,
Porque ele sabe que fazer isso não
vai recuperar a amizade dele com você.
потому что тогда не сможет
 с тобой помириться.
