STFU PEOPLE! A teacher's job is to teach students, not to make love to them. If a student has a crush on a teacher, it's not normal. Maybe because of PUBERTY, but if the teacher knows it all but still has crushes or romantic feelings on the student, it's not normal. Even though this is just a MANHWA, IF A MINOR READS THIS, THEY WILL THINK THAT IT IS NORMAL TO HAVE ROMANTIC RELATIONSHIPS WITH THEIR TEACHERS!!
