Liking this so far. It's korean so this will have romance. Double checked on NovelUpdates and it does have [Slow Romance]. I hope it's not sh1tty at least.
Also, his best friend seems fine. Though at first I thought he was stupid for telling someone, I immediately thought back that that's his bff. If they trust each other that much enough for MC to tell him, then it's his choice. Though my trust issues and paranoid @ss would NEVER lmao
Plus he doesn't seem that loose lipped? He didn't immediately tell it to his sister when MC was being weird and he caught on? so hoping for a strong friendship in the long run!
