JUST LEAVE HIM ALONE AND GO AFTER THE DAD WHO ACTUALLY TOOK OUT THE LOAN!!!!!
And Mr. Yeon.... TAKE BETTER CARE OF THE GUY WHO YOU'RE USING FOR SEX! Buy him a new phone. Make sure his fridge is stocked. Make sure he has weather appropriate clothes. Give him a black card. Pay off the rest of his tuition until he graduates! All this would probably not make a difference to your bank account.
I know Yeomin would try to refuse it, but he might accept it if you sincerely asked him to accept the gifts.
I never understood how office workers have to go to work on the weekends in manga. It's the weekend. Business days are Mon-Fri.
That's not a manga thing, it's a Japan thing. It's pretty common practice for companies in Japan to require salarymen to work 6 days a week, so that includes Saturdays. I read somewhere that there are still some companies them that give their employees the whole weekend. Other than that, Monday-Saturday is typically observed as a full work week in Japan.
In IT industry, sometimes you have to work saturday as well if we have deployments. But usually just 5x a week.
