The manga has an interesting proposal, it's just a shame that it was very rushed and a bit confusing. But it's really funny and worth reading.
I don't hate myself enough to read more than 3 chapters, I read the first one and the last two and how mentally exhausted it made me!
They are a little rushed into the marriage, but I like it.
Such a beautiful story!
About the tattoos:
1) on the neck and shoulder, in French "Vivre sans regrets", it means "live without regrets";
2) on the back, in Latin, "Ab imo pectore", it means "from the bottom of my heart"
It's been a while since I read a manga as bad and confusing as this one.
