"But, I read in novels that other systems can help their host. They can spy, hack, offer items, and help with finding a soulmate. Can you do that too?"
"No."
"(o_o). So what can you do?"
"Nothing."
"눈_눈"
"Well, I can help you improve your skills with experience points and buy items before you enter the world and record your experience points."
"Wait, if there is energy points, level points, experience points, what do I use to exchange items and skills with?"
"Experience points are used on skills. You will also get crystal coins by completing tasks. This is the universal money that you can use to exchange currency in all the worlds. You can also exchange world currency with crystal coins."
"Why do I need to buy items before entering the world?"
"Well, for a realistic performance during a world travelling, the host is only allowed one squared meter storage space and must prepare well before entering."
"Why? Aren't going to be with me?"
"No. I won't. You are on your own. You need to grow up on your own and not by relying on the system. I am not a babysitter."
"Fine. So I will get the world information, will I also have a plot?"
"No."
"(╯°□°）╯︵ ┻━┻. This is too much. This is a scam. I barely accept all the previous aspects, but no plot!!! How am I going to complete the tasks?"
"Well, you have information on the general trend of the world and the cause of death of your character when you are a beginner. A word of advice, you better not harm the main protagonists. By the way, you cannot break the contract."
"Why?"
"You will be obliviated."
"(╥_╥)"
"It's your fault for not asking the clauses of the contract."
"(ノToT)ノ ~┻┻"
"Another thing to beware is that you better not fall in love."
