[Love Chocolat] You like my muscles, don't you?

(With those obscene muscles... I'm falling for pleasure!? Me!?)
Whenever Akane returns home, Okada-kun, a Tsugaru dialect university student from next door, who forgot his key, is always waiting for her.
It all started by chance. At first she felt sorry for him and let him stay over, but gradually his frequency increased and Okada's demands escalated!
“You like my muscles, right?”
I wanted to be able to resist with my rationality in the face of his beautiful sculpted muscles...I wanted to...I wanted to.
The muscles of the mountain range alone were too much, but Okada-kun, whom I thought of as my little brother, declared, "I really want to have sex with you!
"So cute, you fell off so easily."
He's selfish and cute, but he's more sexy than anyone else... It seems like Okada-kun has a "secret" too...?
