Poor Usami. She is gonna be so embarrassed when she finds out.
There is a typo on page 10 bottom right panel. Being instead of begin. The first that comes to mind when I read or hear Dark Brotherhood is Elder Scrolls. So maybe a game reference.
... this could be utilized by Uchimaki for a (highly effective) real marriage proposal idea in the future 🤔... someone feel like making a doujin out of this?
Man, I feel sorry for Usami. She's gonna work herself up into a delusional fantasy about Uchimaki giving her a ring only to crash and burn when she finds out the truth. How many times does this sort of thing have to happen to her before she gives up on him?
