Were we expecting to finally know? Maybe just a tiny bit. But naaaah, that's Koi to Uso we're talking about. The author will probably only tell us her secret on his dying breath. Sometimes I wonder for how long they've been running around the bush, been years now since we really saw any romance things besides character stupidily hurting themselves with basically nothing readers know.
One thing I must say tho, is that whe're only on vol 10. It seems hella long because it's only 6 pages and a biweekly but this is still not that long in terms on vol that they've been running around that secret.
