[ These are side stories from volume 4. One is Gaku’s while the other is Seishin. This happened after Yuulin’s vacation trip back to her hometown.]
Side story 1: Gaku At town no. 1, Gaku’s underlings ask Gaku if it is okay to just let Yuulin be taken away and shouldn’t it be better if they think of a way to get her back from that bad deceiving guy whom Yuulin owed money from. [<- referring to Reishou] Gaku complains that they are too noisy, just let Yuulin go since he doesn’t want to care anymore. One of the underling protests that before, Gaku is quite worried about Yuulin’s work at the palace. Gaku angrily denies that he’s worried but rather, he is only a bit concerned. “Upon seeing her, I’ve learned that she is quite energetic. Since I’m aware of that, then, making her cry at least once is also good. That stupid woman.” The three guys mutter, “Boss..” Then, Gaku reprimands the underlings not to recklessly gossip when Yuulin comes back and anyway, she will definitely come crying back. “She is really a troublesome child that needs to be cared of.” The underlings cry that Gaku’s love is really deep. Gaku angrily shouts that it isn’t love, but they didn’t listen to him. =P In town no. 2, Seishin happily tells Gaku that after returning to the palace, Yuulin wrote a letter to him and it is the same as before. Gaku says is that so. While glaring, Gaku asks what the contents of the letter are, and did it mention about that hoodlum. Holding the letter, Seishin asks if he wants to read it. It reads, “Seishin, how are you? I am currently working hard. You are well, right? Are you eating right? Are you having fun studying? Are there any guys who are giving you trouble at school? If there is, I’ll beat him up. So, tell me okay? You are so nice, considerate and such a cute child. So, I’m always worried about you. And also, like what I’ve always told you, about father’s loan, I’ll definitely think of a way to resolve it. But if the situation is dangerous, then you have to quickly run away, understand?” Seishin tells Gaku that it is the same as before. Gaku mutters that it is splendid and Yuulin wrote only about Seishin. A note says that Yuulin is totally a burakon [(younger) brother complex]. Back at the palace, Seishin wrote a letter to his sister that their father and Ki Gaku are still the same as before. A note says that there is a messenger who helps them in exchanging letters. While Reishou is looking over her shoulder, Yuulin angrily complains that it isn’t necessary to mention about Gaku. It is just a waste of paper to write about Gaku since that guy will absolutely not get sick since he is a stubborn loan shark. “Just thinking of him puts me in bad temper.” Puppy Reishou sighs and mutters that their relationship is really good. This surprises Yuulin that she wonders why Reishou suddenly became like that. Note says that Yuulin totally doesn’t understand the reason for His Puppy Majesty’s dejection. End.
