This was a pretty entertaining one-shot manga. I think it could have been much better if it was longer since the ending was kind of abrupt, but for a short story, it was really good.
I loved how the Aunt did things. She was pretty eccentric.
GB was probably my favorite character. He was just too adorable and fun.
Art-wise, everything was really good except expressions. It was often difficult to tell what emotion the characters were feeling.
Story-wise, could have been better, but like I said, since it was a one-shot it had to be packed in. So with the space given, the artist did a pretty good job.
Some strange or unexpected things happened, and sometimes the characters acted unexpectedly in a comedic way, so I really enjoyed this manhwa.
If you like typical, kind of silly, romantic-comedy manhwa, this should fit the bill nicely!
