According to Alpin, Alpin and Lileas's mother passed away after Lileas' birth. Alpin raised Lileas during their childhood. Their father lived in a city, raising money for the two children. Since they were hardly with their parents, they spent most of their time on their grandfather's farm. This may be the place where Alpin first took interest in gardening. He eventually developed love for all of nature and "naturally" became a gardener. He never seems to take a day off in gardening, and perhaps never once slacked off. According to his philosophy below:
If a gardener is lazy,
even for a single day,
it will show in his work.
No, Gardeners much[sic] be diligent
and meticulous.
This might be the reason he never take breaks while working in the garden.
At one point, Alpin worked a General Store, being able to say the prices right from the top of his head. Alpin also worked for a weapon shop another point in his life, picking up heavy equipment and perhaps moving them to other local vendors or attempted to sell them for the person he worked for. When he looks back at it, he smiles to himself. He also once took a part of a potion study. Though he was paid well, he ended up writhed with pain for days, as well as potion poisoning. He doesn't not seem to be much of a spender, saving every piece of gold he earns.
Alpin's outfit is a slightly modified Natural Vest Wear. He also wears an old straw hat (which is part of the clothing), which has a lot of sentimental value. He never seems to wear any other clothes at all. In fact, he wears his uniform whereever he goes, being scolded by Lileas from time to time. Alpin also wears gloves that were a gift from his sister. He never goes gardening without the gloves, which was received during the Lughnasadh Festival.
