What does this mean in English, very few words (Screenshot inside)?
illusional romance

梦幻：梦是睡觉时的妄想，幻是魔术师的表演。二个都是虚假的。

情缘：情通常指男女爱情，缘是缘分(the fate, the lot, the second cause)。

补充：

'梦幻' also means '美好的'(extraordinary, too good to be true)。
For example: 梦幻音乐。 It means wonderful music instead of fake music.

So, it depends on the whole story.
'梦幻情缘' may be a beautiful love when the story is real and good.
