I Can't Be the Prissy Prince's Body Pillow!

Yuzu, an office worker, works part-time even though her company doesn't allow it. The company's vice-president, Hiroaki, who is nicknamed the "Prissy Prince," finds out about this, but he actually suffers from insomnia. Seeing Yuzu's soft body, Hiroaki asks her to be his "body pillow" in exchange for overlooking her breaking the rules. Yuzu works hard to help him sleep well. Hiroaki opens up to her and hands her the key to his apartment, but one day, when he arrives late after entertaining a business client, she learns of his carnivorous side! Their hearts grow closer despite their differences, but there's a major challenge awaiting them! Source: MangaPlaza
