Hajimete, Hajimemashita.

Overview

"I don't want anyone else to see how cute you are." After his father's death, Toki worked hard to support his four younger brothers and mother. After his mother remarries, her deepest wish is for Toki to live for his own sake. As his family wishes, Toki enrolled in a correspondence high school at 27. There, he meets his younger brother's friend and actor, Takara. The overly touchy but caring Takara wants Toki to be his friend, rather than an "older brother." It was at that moment that Toki's budding feelings began. A touching and heartwarming story of first love as they search for happiness. (Source: MangaPlaza)
