love bubble 热恋期

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指刚刚恋爱的那段时间，所有的工作、计划、与别人的交流以及生活中需要做的事情都被忽略，一心只想跟爱的人在一起，也就是我们所说的“热恋期”。

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.

杰克和吉尔刚见面就进入密集热恋期，他们一整天不吃饭，也不睡觉，不过，他们好像完全不在意。
