Gintoki lets Hijikata have it, but under one condition; he has to confess "I like you".

But when Hijikata gets the chance to turn everything around with a confession drug, he cannot resist the temptation of finding out Gintoki's true heart.

From the author:
It's my first time releasing a Ginhiji book. Since release and selling out, more than a year has passed. Because I have no plans to release a reprint, please allow me to reupload this work via web again. Thanks a lot to the people that had gotten the book in paper! It's super rough and even more embarrassingly messy, but I'll be blessed if you find yourself enjoying it...!!
