>>2 too deep. and please use common words, not everyone talks like you.
>>1 I personally think that its better to have at least one common interest when it comes to having a relationship with someone, and being both of you inclined to creating stories/novel/or even manga/manhwa is even better.
Pros:
You get to enjoy each other's company
You always have something to talk about
Cons:
You'll get bored of each other
One of you might dominate each other as to which plot goes better with the story because you have different opinion in mind (esp if you're the writer)
(I almost had a relationship with someone but his tastes and hobbies are too different from mine and its hard getting comfortable with each other. So its still better that you have at least one thing in common.)
every relationship differs but its up to the two of you of how you're gonna tolerate each other.
