I watched this Anime and I forgot its name

I watched this Anime a few years Vor 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 Von a monkey. And the house owner would accidentaly see him naked because he forgot to lock the door. the female lead falls on oben, nach oben of him and they would accidently KISS and a few days later the male lead saw the female lead eating a flavoured Essen and remembers that the tastes like the flavour (from the kiss) please help. Its also a highschool anime
