I watched this 아니메 and I forgot its name

I watched this 아니메 a few years 이전 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 의해 a monkey. And the house owner would accidentaly see him naked because he forgot to lock the door. the female lead falls on 상단, 맨 위로 of him and they would accidently 키스 and a few days later the male lead saw the female lead eating a flavoured 음식 and remembers that the tastes like the flavour (from the kiss) please help. Its also a highschool anime
