This manga fits on the "lovey-dovey couple exploring their love together" category of romance, and it's possibly one of the best out there at the moment.
The story revolves around the male and female lead affirming their feelings for each other, and getting used to the new feelings that sometimes overpower them. Both are helplessly in love with each other, and even though they're quite innocent regarding love, they're not shy to explore where does it lead them to. It's really heartwarming to see that pure, innocent love they have and their ways to deal and communicate about it.
Fortunately, the dramas that occur are all reasonable relationship stuff, and all the cliché drama that happen (quite rarely) are not dragged through multiple chapters, rather, they are dealt with quickly and maturely. All in all, the most that happens are both of them developing and nurturing the love they have for each other, sometimes having some common headbutts that just are bound to happen when they decided to share their lives together.
It's extremely cute, and neither of them are shy about exploring their romance, while also respecting each other's boundaries. It really makes you feel all the joy of falling in love, so I would definitely recommend in case you want to enjoy a cute and simple manga about two lovebirds.
