Yukinoshita Haruno: Today, you have to choose between me and Yukino! Otherwise, you are not going home.
Shizuka-sensei: Young lady, you're something else! You actually seduced your own student, so marry me already!
Kasumigaoka Utaha: Sensei, I'd like you to take a look at my new book.
Some blonde loser: You have to choose between me and Mashiro today, or I'll draw you into my next doujin!
Kal'tsit: Long time no see, Wang Gu. I wonder if you still remember your promise to me, the promise that you'd marry me and take me home.
Ma Dingding: Hehe, Big Sister Wang Gu, Ding Ding Ding Ding.
