喜你而已
[xĭ nĭ ér yĭ]
This username expresses a simple, joyful affection for someone, without overcomplication. '喜' means joy or happiness; '你' refers to 'you,' and '而已' at the end can have a tone of 'that’s all.' It conveys the emotion as if to say: loving you is merely a pleasant thing I hold in my heart.
