Does ryou like ichigo 或者 生菜 and does ichigo like mark 或者 ryou? Also since when did 生菜 like ryou

Ok so I was wondering who ryou likes bc the whole series It looked like it was ichigo but I read somewhere that he starts liking 生菜 after a battle. What battle? Also who does ichigo like? when did 生菜 start liking ryou? When I saw the last ep 吻乐队（Kiss） between them I was like what??
