Indeed. Has the author disclosed the possible reasons, presumably psychological why the character is always masked? Or maybe they are going for a supernatural feel by making out that his stage mask was observed onto his face, as it became his only identity and enables him to be confident. To quote Oscar Wilde: " Give him a mask, and he will tell you the truth."
Here are a few mangas where the M.C was masked that actually convey the reasoning behind their crutch

Or maybe I've just missed the entire point of the plot, it's been a while since I've read it. Maybe he actually is some sort of tiger thing and he only tells people he is wearing a mask to deflect any superstition. idk

i personally don't care for the sex. like that's just the extra stuff that comes with the story to me. but i really dont understand their relationship. (i have not read the updates). the last time i read this they were roommates on good terms who had one oral sexual intercourse. the recent updates the past few weeks showed a somewhat steady relationship of friendship and then nothing much else. its like the author is producing random events for the two without actually tying it together with their relationship imo. maybe it is the slow updates that cause for us readers to start seeing the manga differently. i will bet reading everything in one go from start to end will make this a better read for everyone.
This manga to me has gotten a little bit Boring lately... like the first few chapters where so exciting and like there was a dick scene which was mhmhmhmhm ( ° ʖ °) but like idk not much going on now
