Not in the right order, I'm sure, but I think it goes: Slowlife is SunnyDays, Tsukiakari Michishirube, Seishounen no Miryoku/The Attractions of Youth, Hattentojouna I Love You/A backward I love you, Aishiteru to ka suki da to ka, Sekinin totte Kudasai ne, Onsen Ryojou Yumekibun, Utamonogatari no Utawasure, Now Imprinting. I found these on myreadingmanga.
