4 petals, white with hint of purple, leaves pea-like but no tendrils
No interactions present.
The flower is not that of a pea or bean. The leaves of cultivated peas are round and fairly nondescript. Peas in general can have any of very many forms of leaf.
Yes the flowers are obviously not that of a legume, however the leaves are similar in construction to those of a vetch, being compound, pinnate and opposite
Cardamine sp./hybrid/cultivar is a good fit for the flower and this time of year (if they are around 15mm or a little bigger across), but not a particularly good fit to your description of the leaf.
