Otaku Onzoushi to 2.5 Jigen Hanayome: Kare no Oshi Chara ni Sokkuri na Seide Dekiaisaretemasu

Airi, a daughter of a small bakery owner, was hired by a large food producing company. It was a dream-come-true for her. On her way home, she was suddenly taken to the CEO's house to meet their son, Akinari. He was an Otaku, loving this character "Love-chan" so much that he refused to marry anyone in the real world. And this Love-chan looked exactly like Airi...! Airi starts to live with Akinari, and in return her father's bakery gets support from her company. Akinari is handsome and sweet...Airi starts to have feelings for him while working close to him in the company. But she is not sure...does Akinari loves her, or just Love-chan!? (Source: Kadokawa)
