Alya Sometimes Hides Her Feelings in Russian, Vol. 4

Summer vacation has arrived, so Masachika and Alya get to spend some time together away from the hubbub of school. However...studying at Masachika's place is the only thing they've been doing! Alya takes it upon herself to teach Masachika how to treat a woman, but once those two get into it, neither is willing to back down. Summer break also means they're going on the student council's trip to the beach! Swimsuits baring skin, dips in the hot spring, and a game of King really heat things up! But what will happen when certain secrets slip?
