Otonari no Nie

Kazu reunites with his childhood friend, Shion, for the first time in a long while. He falls for her all over again as he realizes she’s become even more beautiful, but despite this long-awaited reunion, she seems somehow distant… Shion is harboring a secret Kazu knows nothing about. Though Shion also harbors secret feelings for Kazu, her father, with practiced ease, runs his hands over her sensitive spots and forces her to be “friendly” with him once again today…!
