"We're New at This" is a romantic comedy manga that explores the challenges and humorous situations faced by a newlywed couple navigating their first year of marriage. The story centers on Ikuma Takanashi, a reserved and hardworking salaryman, and Sumika Hoshino, a cheerful and somewhat naive office worker. The two characters, who had little romantic experience prior to their marriage, find themselves learning about intimacy, communication, and the complexities of married life together.

The narrative begins with Ikuma and Sumika deciding to marry after a brief courtship, driven by mutual affection but limited understanding of each other’s habits and personalities. Their inexperience in relationships leads to awkward and often comedic situations as they attempt to build a life together. From figuring out household responsibilities to navigating physical intimacy, the couple faces a series of relatable and lighthearted challenges.

Ikuma is portrayed as earnest but socially awkward, often struggling to express his feelings openly. Sumika, on the other hand, is more expressive but lacks confidence in her ability to be a good wife, frequently overthinking her actions. Their dynamic creates a balance of humor and tenderness as they support each other through misunderstandings and personal growth.

The manga delves into everyday scenarios, such as cooking meals, managing finances, and dealing with in-laws, while also addressing deeper themes like trust, vulnerability, and the importance of communication in a relationship. The couple’s journey is marked by small victories and occasional setbacks, reflecting the realistic ups and downs of marriage.

Supporting characters, including friends, coworkers, and family members, occasionally appear to provide advice or add to the comedic tension. These interactions highlight the contrast between Ikuma and Sumika’s relationship and those of more experienced couples, further emphasizing their unique journey.

The tone remains consistently light and humorous, with moments of genuine emotional connection that underscore the couple’s growing bond. The story avoids melodrama, instead focusing on the everyday realities of marriage and the gradual development of Ikuma and Sumika’s relationship. Through its relatable scenarios and endearing characters, "We're New at This" offers a charming exploration of love, partnership, and the learning curve of married life.
