I watched this Anime and I forgot its name

I watched this Anime a few years lalu now I forgot its name and I only watched 2 eps of it. The male lead has a younger brother and they have brown hair i guess. In the first ep the male and the female leads will meet in the forest because the male lead's brother's hat gets stolen sejak a monkey. And the house owner would accidentaly see him naked because he forgot to lock the door. the female lead falls on bahagian, atas of him and they would accidently Ciuman and a few days later the male lead saw the female lead eating a flavoured Makanan and remembers that the tastes like the flavour (from the kiss) please help. Its also a highschool anime
