Manga Like Mad With Love!

Mad with Love! (Wakasama go Ranshin!, 若様ご乱心!) Sakae Kurashina and Natsuhiko Kenjou are childhood friends who attend a school built on land where a castle used to stand. The Kurashina family even used to be lords, but all that means nothing now, hundreds of years later. One night, Natsuhiko comes to find his best friend falling from the roof of the school building. Rushed to the hospital, Natsuhiko is relieved to learn that Sakae is ultimately saved. But when he comes to, Sakae is... not the Sakae that Natsuhiko knows and loves! What's going on with his best friend!? Is this Sakae who speaks like he belongs in old Japan really the same Sakae that fell from the roof!? The Path of a Secretary (Hisho no Kokoroe, 秘書の心得) Nonoyama is the personal secretary of his company's CEO, Mr. Maki. He was specifically selected because of his naivety and innocent nature. When one of Mr. Maki's old friends visits the office from abroad, he's brought with him a suspicious youth-claiming elixir. When Mr. Maki drinks it and some of it goes into Nonoyama's mouth, will this personal secretary become a 5 year old boy in a suit!? It seems to have worked for Mr. Maki! (Source: Futekiya)
