At a glance, it looks like the series is just some fanservice-ecchi kind but it actually a pretty wholesome romance with a great interaction/development between the mc and fmc.
Both series take place in office and casual places.
Ase to Sekken starts the series where the main characters are in a relationship pretty early in the series while Bijin Onna Joushi Takizawa-san is more of a traditional way but with pretty fast development.
