Kyou wa Kaisha Yasumimasu., Love Rerun Recommendations
Stories envolving a virgin in her thirties, with a boring looks, that met a guy who accepts them. Both leads loose their memories (not in the same way) so they cant remember If they did anything at all.
Love Rerun is a bit sweeter because of the friendly and honest main guy.
• Both are about hardworking women over their thirties who are still virgins and wear glasses (that's relevant).
• Both main characters get involved in a love triangle with a guy around their age with malicious look and a rather round-eyed younger fellow.
• Both main characters lose their memories in some way.
I think Love Rerun is better judging by what I've read from Kyou wa Kaisha Yasumimasu., but Tanokura Yuuto, from the latter series, is the most worthy character amongst all here.
