Mukidashi no Koi
Nonokawa, a salary man in the midst of burn out, hears that drought has dried up a reservoir that had been constructed to flood his old village, and returns to look at the elementary school which is now exposed. That was where he had a brief but traumatic encounter with his childhood friend, Kouya, who clearly shares his feelings, after which he ran to the city, sealing all those feelings away. A cute story about regret and repression.

Love Me Thru the Night
Two stories by Konno Keiko. (1) Two childhood friends stay in touch long after leaving school, traveling long distances to stay with each other, brushing off their lovers in order to make time for each other and, yet, never realizing what this says about their true feelings. (2) A man plays at a relationship with a woman until he can make the gay man with whom he's in love commit with his full feelings. Slice-of-life stories, not necessarily sympathetic characters especially in the second story, but realistic.
Toki no Maigo o Sagashite!
