Dear, your story is so great! I never know you had this potential in you! Keep it up! Don't give up!
A little suggestion, the story 'HSSG' look better without the picture in it, you can put link at the end of the story for the reader to see, and put short note down below the story like ' you can refer at the end of this chapter for FL's outfit or house or room'.
And I think you should use your own character name instead of the korean idol. And you can just say that the character was as handsome as the korean idol but with different vibes or look or style. Explore your creativity.
Best wishes and lucks!
