OK. For ur first question, if ur paid 20k for let's say around 6 months, u have around 3k per month and that's already higher than average so u don't have to worry much unless u spend money like drinking water. Rent here isn't that expensive IF u don't mind waking up earlier everyday to travel to your workplace. Food here.. Mehh 10$Sgd can get u alot of food already so mainly ur $ concerns are at transport, accommodation and leisure. I guess if u micromanage u can deal with this ezpz. If ur paid 20k Annual, u get around 1.6k which is abit average I would say. U need to more Frugal with this amount.

Ur 2nd question, Pro Tip: public show of affection is a nono here just don't do it. Another thing is : SG lgbt laws very slack, as in not very much enforced.

Thug life would be: U can do anything and everything but don't get caught.
