Is that yumi?? The manager that shuuna called?

Yup the manager guy is yumi but The guy who said manager is not shuuna... tanaka likes to shows that yumi is in osaka. Because he talks in kansai dialect which is a dialect in osaka, where shuna will be transferred.

Sooo... There is a high chance that yumi (ex) and shuuna (present lover) will cross paths.

Oh my! I hope they do meet someday and shuuna will be the bridge for them to settle everything so that kan-chan can move on knowing that yumi is happy with his lover now.
