noun
General term for a romantic or sexual relationship, often with a slightly literary or old-fashioned feel.

noun
Specifically refers to a romantic or erotic scene in kabuki theater.
この歌舞伎の濡れ事はとても美しく演じられた。
The love scene in this kabuki play was performed very beautifully.
恋愛 is the standard modern word for romantic love or a love affair, while 濡れ事 is more literary and can carry a nuance of physical intimacy or scandal.
情事 also means love affair or sexual relationship, but is more neutral and common than 濡れ事, which has a slightly old-fashioned or theatrical flavor.
Compound of 濡れ (nure, 'wet', from verb 濡れる nureru) and 事 (koto, 'thing, matter'). The 'wet' element metaphorically suggests physical intimacy or emotional entanglement. The exact historical derivation is uncertain.
