Like others mentioned before, you just started and have 3 episodes. Novels are about self promotion 90% of the time. Don't expect to be a big hit wonder just by writting. Writting is just 10% of the work you must put.
That being said Fantasy is your main genre so many people will expect adventures. You also used the genre slice of life.
You may want to rethink which is your main genre according to tapas public.
This will be hard even I don't fully get where my novel will fit (as main genre) but I plan to ask for advice once I upload it.
Note: Judging by your summary I would say your main genre should be slice of life followed by mystery (or vice versa) and then fantasy (if there is fantasy?)
