Itadakimasu, Gochisou-sama
Really has an atmosphere of "slice of life" and isn't so very plot heavy but that's a good thing. Cute pairings, and nice art.

He takes him in and feeds Haru, and despite their 12 year age gap, Haru confesses to the sweet hearted Hiroto who has a hard time saying no. The second couple is Kouta and Koyama Riku, who were lovers since highschool and also live in the same house as Hiroto.
