想你莫名其妙的傻笑
[xiăng nĭ mò míng qí miào de shă xiào]
'Thinking of You and Mysteriously Smiling Foolishly' means feeling a sudden urge to smile foolishly for no particular reason while thinking about a specific person. It usually occurs during early stages of crush or relationship when recalling a person makes us feel light-hearted and happy without logic.
