Love bubble is the period of time immediately after falling in love when one's obligations, plans, communication with others, and sometimes necessities become neglected due to the desire to spend time with the loved one.

Love bubble指剛剛戀愛的那段時間，所有的工作、計劃、與別人的交流以及生活中需要做的事情都被忽略，一心只想跟愛的人在一起，也就是我們所說的“熱戀期”。

For example:

Upon meeting, Jack and Jill entered a particularly severe love bubble where they forgot to eat or sleep for an entire day, but it was of no matter to them.

杰克和吉爾剛見面就進入密集熱戀期，他們一整天不吃飯，也不睡覺，不過，他們好像完全不在意。
