Ikemen ni Tensei shita kedo, Cheat wa Dekimasen shita.

Koganei, after being rejected by a girl, is struck by a car and awakens in a fantasy world as Theodore Goldberg, the eldest son of a noble family. Expecting to gain a powerful ability typical of isekai stories, he attempts to access a status screen but finds none exists. He tries to use advanced magic but is too young to learn it. His attempts at sword training prove ineffective. He then tries to introduce modern technology, only to discover that the world already has magical equivalents. Theodore lacks strength, intelligence, and good looks, leaving him confused about his purpose in this world and why he was reborn without any advantages.
