wet, be watered, profit by, receive benefits, favor, charm, steep
潤 centers on moisture bringing enrichment: being wet or steeped, and by extension receiving benefits, profit, or charm that flows from that moisture.
潤 combines 氵 (water) with 閏, which likely contributes the sound and the idea of surplus or intercalation, suggesting water that enriches or moistens.
Water 氵 flows into the intercalary month 閏, soaking the calendar and bringing extra benefits and charm.
For ジュン, imagine a June rain that wets everything and brings profit to the crops: June -> ジュン.
