Giri choco

Giri choco is chocolate given by women to men on Valentine's Day in Japan as a customary gift. Unlike honmei choco, which is given to romantic partners, giri choco is a type of chocolate that women give to male co-workers, bosses, and acquaintances out of appreciation and politeness. Men generally reciprocate by giving women gifts on White Day, which is celebrated on March 14.
