恋AIフラグ~AIが理想の恋人を選んでくれるマッチングアプリを使ったら異世界の勇者とマッチングした~ / Ren AI Flag: When I Used a Matching App Where AI Chooses Your Ideal Lover, I Matched with a Hero from Another World

Mido Ryota is enjoying the campus life he has always wanted, but he still cannot find a girlfriend. As a last hope, he tries Ren AI Flag, a matching app recommended by a friend that uses AI to choose an ideal partner, and gets matched with Lilia, a beautiful blonde girl. There is one surprise: Lilia is a hero from another world. Though Ryota hoped to win her over in an ordinary romance, he finds himself under pressure to pursue a relationship with marriage in mind—and the two end up living together. Their story begins as an unusual youth romantic comedy about a university student longing for a normal love life.
