Synopsis: The Night I Drowned in His Obsession: The Devoted Ex I Shattered

"This time I'll make sure we don't fall out." My ex-boyfriend loves me more than I can handle... I want him to fuck me so hard he breaks me! On Christmas Eve, Riko loses her fiancé and her engagement ring to her friend. Lost and depressed, she runs into her ex-boyfriend Yuzuki. 10 years ago, Riko dumped him because his feelings were too heavy for her. Now, he offers her a shoulder to lean on, but she notices a ring on his left hand. She tries to turn him away, thinking that it'd be disrespectful to his wife, but he says, "I'm sorry... I know it's heavy, but I couldn't bring myself to take it off." Could it be one of the matching rings they had when they dated ten years ago?! This time, she can't turn him down!
