There is no specific phrase in English that directly corresponds to the concept of "the one hundredth day feels like a fresh love". However, we can express the sentiment in other ways.
One way to convey a similar idea is to say that "even after one hundred days, the love still feels as intense as when it first began." This emphasizes the lasting passion and excitement in a relationship, even after a significant amount of time has passed. It implies that the couple's connection remains strong and reminiscent of the early stages of falling in love.
Furthermore, we can use the phrase "honeymoon phase" to describe the initial phase of a relationship where everything feels exciting and new. Although it is not specific to the hundredth day, it signifies the early stages of a relationship where the couple experiences intense romantic feelings and a deep connection. Using this term, we can say that "even after one hundred days, they are still in the honeymoon phase, as their love feels as fresh and exciting as ever."
It is important to note that the notion of a hundredth day feeling like the beginning of a relationship is more commonly found in certain cultures or traditions that celebrate milestones such as anniversaries or milestones in relationships. However, these concepts may not have direct equivalents in English idioms or phrases.
In conclusion, while English does not have a direct phrase that mirrors the concept of "the one hundredth day feeling like a fresh love," we can convey the sentiment by highlighting the enduring intensity of love after a significant period or by referring to the early stages of a relationship as the "honeymoon phase." It is essential to consider cultural differences in expressing these concepts accurately in English.
