Summer's in full swing, and it's not just the temperature that's heating up! When the group takes summer jobs at a seaside cafe, long days in the sun bring them closer together - but there's still plenty of opportunities for confusion and chaos alongside all the romance. Misunderstandings, mixed signals, and flustered hearts keep everyone on edge, especially as feelings begin to show in unexpected ways. From surprise photo shoots to moonlit fireworks, every moment brings them one step closer... or two steps back. The romantic comedy of crossed wires and cross-dressing continues in this breezy, heart-fluttering fifth volume of How I Attended an All-Guys' Mixer!
