Bishuu Abekobe Iekai de Busaiku Outaishi to Kekkon shitai!

While battling a deadly illness, Cocolette Blossom suddenly recalls her past life—a lonely existence spent fantasizing about her handsome 2D faves. Determined to finally live out her romantic dreams, she resolves to marry a real-life hottie this time around. But in her new world, "hotties" don't exactly meet her expectations. In fact, they look like absolute monsters—and the guys who actually catch her eye? They're considered hideous and total social outcasts! Undeterred, Cocolette sets out to snag her ideal man in Crown Prince Raphael. Yet even though they both fall for each other at first sight, the "hideous" Prince Raphael is weighed down by a dark past and cripplingly low self-esteem. With wedding bells still ringing, can Cocolette boost her prince charming's confidence enough to prove her love is real?
