I watched this anime and I forgot its name

I watched this anime a few years nakaraan 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 sa pamamagitan ng a monkey. And the house owner would accidentaly see him naked because he forgot to lock the door. the female lead falls on tuktok of him and they would accidently halik and a few days later the male lead saw the female lead eating a flavoured pagkain and remembers that the tastes like the flavour (from the kiss) please help. Its also a highschool anime
