My Entire Space Is a Mosaic

Song Letian was an optimist by nature, just as his name suggested. But fate had it in for him, and not even his cheerful name could save him.

For example: Other people kick a stone, pick it up, and discover a rare uncut gemstone. When he kicks one, he trips and transmigrates.

Another example: Other people transmigrate as princes, generals, or rich young masters. He transmigrates as a penniless quasi-widow whose fiance is somewhere out there, but whom she never gets to see.

And another: Other people bring along a space with spirit springs, wealth, and everything they could want. His space is entirely undeveloped, covered in blocks of mosaics.

And another... Forget it. There's no point comparing.

To sum up:

An optimistic unlucky fellow transmigrates into the body of a pauper. His space is all mosaics, and to use it, he has to complete quests to unlock it. The quests include, but aren't limited to, running errands, farming, hunting, sweet-talking, kissing, hugging, being carried around, and... something that's a little hard to explain, as well as... something that can't really be talked about.

The legendary husband is supposedly strong and sturdy, tall and handsome, brilliant in both pen and sword, and unbelievably capable. At the same time, he's frail and sickly, breathtakingly beautiful, and incredibly clever. Of course, all of that is only according to the rumors.

There are heaps of oddball relatives. Life is a miserable struggle of wits, but somehow it still manages to be lively and eventful.

Song Letian: "Who am I supposed to kiss?"

Requirement to unlock plot of land No. N in the space: Rule the world.

Husband: "I'll rule the world. You can be the world."

Bonus scene:

Song Letian: "Brother Hai, give me a hug."

After Ming Hai hugs him, he leans in for a kiss. Song Letian: "All right, you can go now."

Song Letian: "Brother Hai, kiss me."

After Ming Hai kisses him, he tries for a second one. Song Letian: "All right, you can go now."

Song Letian: "Brother Hai..."

Ming Hai: "What quest are you doing today?"
