Kase-san and Yamada Vol. 4

After the events of the first five Kase-san and... manga volumes, Kase-san and Yamada are now university students. Yamada's working diligently in her horticulture program, while Kase-san is training hard at her university. There might be a long train ride between their schools and hectic new schedules to plan around, but they'll always make time for each other!
