イノコリ先生 (Inokori Sensei)

Background
Teacher, here's HoneyWorks┗ "Inokori Sensei" is an original song that was used as a debut demo featuring flower, and is part of HoneyWorks' Confession Executive Committee Love Series. The song portrays the complex relationship between Serizawa Haruki and his teacher, Akechi Saku, who also happens to be a former childhood friend.

Feeling belittled by his teacher, Haruki is constantly attempting to prove that he is no longer a child, only to get himself into constant trouble in class. However, the truth is revealed that the teacher feels remorse over his incapability to save his best friend, who appears to be Haruki's elder brother. At the end of the song, Haruki realizes the situation, and offers to help his teacher to deal with the guilt in that way that would repair their friendship.

This song has entered the Hall of Fame and reached over a 1,5 million views on YouTube. A version sung by Saku's voice actor, Midorikawa Hikaru, is also featured in HoneyWorks' second major album Boku Ja Dame Desu Ka?.
