Eternal Ring ~Miwaku no Yakusoku~

"I'm not going to ask you to break up with me... for now." "We seem to agree on a lot of things." "Won't you call me 'Teach' just one more time?" After a night of heavy drinking, you wake up in an unfamiliar place... where are you?! A fateful encounter with a headstrong, yet charming man... An office romance with the son of an esteemed family... Even a meeting with the teacher you once looked up to is making your head spin. Which of these men will be the one to promise you love for all eternity? [Translated from official website]
