FUTSUTSUKA NA KYUUKETSUKI DESU GA, SUENAGARAKU YOROSHIKU ONEGAISHIMASU

Itaru is a normal salaryman, but his wife is a vampire! She may look cool and composed, but she loves her husband a lot and is the absolute cutest when she occasionally acts lovestruck. A lovey-dovey, endearingly frustrating and heart-pounding romantic comedy of newlyweds. (Source: Comic Walker, translated) — Description from AniList community (anilist.co).
