apart from people that attracted by the plot and acting, two groups of people will be attracted if it is non-bl but keep the romance...one group is anti-BL but accept bromance, another group is watching bromance but in mind imaging it as BL every seconds both male leads together in the screen...haha
i noticed sometime guys in the drama use kha when talking to a female friend, when he is not trans, not sure why....
i think there is no fix rule for pronouns, such as chan and nu, which mostly use by girls, but sometimes guys using it to make himself special or cute...my thai friend told me this...
