Hima nanode Hajimete Mimasu.

Both Hima nano de Hajimete Mimasu and La Satanica's have a handsome, long haired, highly affectionate, childish character as the love interest and a more serious, kind, short haired protagonist.
Both have a friends turned lovers relationship and are very cute & light.
I can see why a rec was made these two, as their premises (and even characters) are quite similar. We have a long, light haired idiot who is in love with his dark haired tsundere school friend. The tsundere becomes aware of his friend's feelings for him (as well as his own feelings towards his friend), and h doesn't hesitate from hitting his idiot friend to keep him at bay when he gets too handsy with our tsundere.
Both manga are lighthearted reads with cute characters, that are surprisingly well written.
