Chapter 16.5, which is a flashback chapter during Hinata's and Teru's elementary school years:
Hinata: I've got kendo practice today.
Teru: Huh? You do kendo?
Hinata: Yup Always have.
Teru: That's... That's why girls don't like you!! Ahahaha Is that the guy who stinks of sweat!? Eww!
] I don't do because because I want to be popular!
Hinata: Wheee? Look, look! I got a love letter!
Teru: Meh, I'm not interested in that anymore. Don't care...
A short comic after Chapter 16.5:
Hikage: Huh? Sometimes I hug it when I sleep.
Hikage: I can't sleep by myself. I sleep really good when I'm between Black Rabbit and MegaPIG. ♡
Hinata: Hey... what about my doll...
Hikage: You want one too?
Hinata: No... I don't want one, but...
[Caption words: 'This is one side benefit for me,' Teru thinks.]
Hikage: MegaPIG-san... is someone who leaves tyrannical and bullying (although sometimes nice, it's really up to interpretation) comments...
Th... That MegaPIG
MegaPIG: ... Hey, what you thought just now was kind of rude.
] Oh... Sorry...
Hikage: You'll... rely on me...?
Hikage: Now that you mention it... I wonder... what MegaPIG-san looks like in real life... Please teach me a little bit about what you look like in real life. Is it a boy? A girl? Older? Younger? Where do they live? People on the internet are a big puzzle... so I'm excited! Ah! An answer.
MegaPIG: Male. From Osaka. Weight: 200kg. My middle looks like of like face.
[Hikage is shown visibly shocked as she imagines it]
Heh heh... I wonder what kind of reaction Himawari
had to that. [MegaPIG is revealed to be a shy, megane bishounen
] Somehow I'm kind of ashamed of myself!
Teru: Alright! I'll cooperate. Because Black Rabbit, and therefore myself, is his friend.
Hikage: Th... Thank you! ♡
Teru: Well, you can thank me by going on a date with—
[Hinata chucks an eraser at Teru's head]
Teru: What the hell—
] I'll cooperate as well!
Hikage: [reading compiled advice to MegaPIG] Be bright, be cool, be easy to talk to. Look over her gently on occasion. 99% get used to your mutual love. That is all.
.... ARE YOU FRIGGIN STUPID!?
[After Teru suggests that MegaPIG should try direct contact with Hiyori, MegaPIG goes "kyaa!?" after touching hands with her]
Hikage: ... Could it be that MegaPIG-san is... weak...?
Hinata and Teru: This guy's hopeless...
MegaPIG: However, Black Rabbit and the Bright Person's [Hinata's] advice was a waste of time. Really.
MegaPIG: I can't stop my wicked tongue after all!
