A straightforward enough title.
"They scurried off real quick"? Quite the chance they passed up, but I guess it was good for our protagonist since he gets to spend time alone with her instead of having others around.
Great ending though! Ah, so now he finally sees her charm and is actively trying to woo her.
Seems that a little over-indulgence of alcohol (a.k.a. The Ultimate Wingman) on the second night revealed Kenta-kun to be A Man Of Culture, with a high affinity for older women. And perhaps after having experienced the allure of Kanade-san, he no longer needs 'wingman assistance' to step forward and "... take responsibility, right?"
