If you liked the Yume de Aetara manga, the Anime-Planet community thinks you'd like:
The bumbling Yusaku Godai is a ronin – a person who failed his entrance exams. Though eager for a second chance to succeed, Yusaku’s attempts to study for future exams are constantly thwarted by his fellow residents at Maison Ikkoku, who insist on using his apartment for their debauchery and drinking games. Though tempted to call it quits at the house, things change when Maison Ikkoku’s beautiful new building manager, Kyoko, arrives. With plenty of competition from the sidelines and interference from his drunken and provocative neighbors, Yusaku must now focus his energy on winning the girl of his dreams, Kyoko!
These stories are very similar. They are both fairly long romantic comedy stories where the guy and the girl obviously like each other but mishaps and obsticals get in their way.I would say Maison Ikkoku is the much better, realistic, story with better characters. Yume de Aetara has a very wimpy lead and more 2-dimensional characters. If you like one, you will probably like the other though.
