My favorite romcom anime is "Ore Monogatari" or My love story. Im telling you! its so pure and wholesome that it would prompt you to read it's manga and see what happens after the animes last episode! too wholesome too handle! ...oh and if i were to give another recommendation then Yamada-kun and the seven witches, the anime of that is nice and all but id definitely recommend you to read its manga as well. It has romance and comedy in it, but you will see that its story is what is more focused on in both manga and anime.
