I agree to a certain extent. I don't see the point of him having the power in the first place if they were going to randomly take it away. Either have the story completely normal, which I think would've worked fine, or have him regain the power. I was interested in why he lost it and how it could come back (like if it was because he became the one in love, but Jiho was upset with him, so once they reconciled it came back or something).
Even the title of this manhwa is "sound of love", of course is point on the power.
But still the starting of all is because the power. If grey haired dude don't have the power, they will not going out, and the black haired dude will not confess too.
The black haired dude said "if you never asked me to go out, i wil just forget you the time passed".
And if the gray haired dont know that black haired love him, he never fall in love with black haired dude.
And i think when he's lost his power the love story getting better because, the grey haired dude not just do something because black haired dude want it, but because he love him now, i do it with affection.
am i the only one that's bitter that he lost his power? it just feels really.. normal now? that's not bad but i started reading it cause the cool power lol
