I want so bad to know what genre of music the author of this manga listens or who are his/...

Because of my love for this manwha... did find songs that she features in the manwha (in spotify).. yeah obviously...... they are jazz and very relaxing and some are kinda romantic

Can u tell me some of them ?

Can you wait for a while??? There's a lot of them.... hehehe..
I am not a music major maybe describing them might not be accurate but I will try to explain the songs the author did used in my own words

I ahve also exams to study so.....
I am just listening them also for studying

It's okay ... good luck on your exams ... what is your major ?

my major is medicine...

Just listening to the Jazz pieces recommended by the artist.. She got a good taste..
but I am not an expert on this.. just describing this on my own way

My favorite one is Girl from Ipanema... very relaxing actually.. like you can play it when you just want to relax..

The others like Nature Boy, In love in vain, just one of those things, dream a little dream of me and in love in vain... very classic, and kinda poetic in lyrics and it is pretty direct to convey its meaning... like the piece "like someone in love" it is really direct (in vocal version: the song depicts that the person is doing odd and happy like he is in love) that Taeyi said to Seheon that he is flirting, hehehe.....

In a sentimental mood, it is very complex like someone is really in a moody mode playing in it.. it is hard to explain....

Nigthfall and my foolish heart are very mellow music.. This one, you might get into sleep when you are listening into it.... you might consider autumn leaves as well... but when I hear autumn leaves... it is a sad piece, and also my foolish heart, a sad piece

I didn't know about you is one that you can really can a jazz... It has piano and the dominant one is saxophone i guess... A sexy piece...

to be honest... Only when you try to listen them by yourself, you can either appreciate or not mind the pieces..
