I think Seju is from the future and she’s trying to save Seulbi from an accident. The girl Seju draws in the library is probably Seulbi too. And that crow girl is probably saying it's impossible to undo someone's death.
I wanna read more >,< It has the type of art style I like most. Reminds me of animes from Kyoto Animation.
I'll be honest and say that I don't like Min at all. In the first place she shouldn't have started that pretend dating thing when she was already dating professor. Doing it made professor act more desperate. Min ended up hurting Yuna and herself in the process.
Also Seyun is the best girl. Change my mind. Yuna and Seyun broke up but I really want them to get together T_T But it's very unlikely since Min actually started having feelings for Yuna. Everything's so broken rn.
I'll say it once again. Yuna deserves happiness and Seyun should be the one to give her that.
Min and professor broke up. So we can pretty much guess Yuna and Min will make up.
Seyun is a great character. But sadly she is no longer relevant to the plot. So yeah It's Min x Yuna ending (as much as I don't like it)
