Agree on this, Tattoo's could and is in most part an expression to anyones emotion, or even a reflection.
Tattoo's are barely random, or meaningless i should say.
After playing this, kinda have a bit of understanding on her part why she left.
but going through the interlude it is noticable that they grew apart, she even ghosted MC a while.
2nd reason of their reason they haven't spoken a while is ofcourse MC's phone swap... but still...
I'm eager to find out how it play's out and what she'd expect to happen returning like that.
as for me, sticking with the other gals.
I May however do her route when available, on the "other girls" route.
