Lenni's Forest Hometown
On the SwingYou pointed up at the sky from your little swing,
as if telling the whole world:
One day, I'll go and see every place.

Home is PeopleSurrounded by the ones who love you most,
you carry this warmth wherever you go.

spotting the future in your lines of code.
Years later, that small internship spark
bloomed into a real partnership, steady and bold.
From a curious intern in that neon shirt,
to a trusted partner turning ideas into impact—

France · City of Romance
Your French Days ✨You wandered alone through sunlit French streets,
where the canals glowed gold and the mountains hummed soft.
You fell in love with baking cookies,
kneading dough until your thumb was sore,
and snapping endless selfies with your chocolate chips —
each one a little celebration of joy.
You didn't just sightsee, though.
You sat in French classrooms,
learning the language of the place you'd grown to love,
one word, one sentence, one "bonjour" at a time.
France gave you more than pretty views and warm cookies.
It gave you a new voice,
a new hobby,
and a heart that felt a little more at home in the world.

even vowing you'd return here one day to stay.

Your China Travel Diary
From the Forbidden City to the misty hills of Guizhou, from Chengdu's playful warmth to Hangzhou's still lakes, you traced China's soul, city by city. With your love by your side, you wandered old towns, climbed mountains, sipped tea in ancient courtyards, and laughed by the sea. Every stop became a brushstroke in a vivid, endless journey — one that turned a foreign land into a home you carry with you.
And your map is only just beginning to fill.
