K-pop idols and fans have a special connection, though one should bear in mind that there are lines that you can't cross as a fan. However, the following list of K-pop idols crossed that barrier in order to get closer to their fans, and the sweetest, most memorable experience happened between them.

1. SHINee's Jonghyun 

The male idol was indeed the sweetest one when he surprised a working student-barista who was going through a hard time. As Jonghyun showed up, the fan couldn't help herself but shed tears. Jonghyun then comforted her, helped her in her work, and even shared a cup of cold drink with the female fan. As the two got more comfortable with each other, Jonghyun shared his most genuine advice and cheered up the fan who had a hard time living, and said, "You did a good job."

2. INFINITE's Woohyun

On one of Dingo's special series, the male idol surprised a fan named Dan Bi who was working as a part-timer. It was so obvious that Dan Bi was a fan of Woohyun, not to mention the posters and calendars of the idol were all over her room. As they talked about the problematic life of Dan Bi, Woohyun then took a picture with the idol, as the male idol initiated, and he brought his fan to his mom's restaurant, claiming, "You are the first girl that I've brought here."

The date was fast yet memorable, but surely, Dan Bi will forever treasure her precious encounter with Woohyun.

3. EXO's Chen

Often called the "fanmeet boyfriend" of EXO-Ls, Chen will always be one of the sweetest members of the group. Not only he is caring towards his fans during fan meetings, but he also talks with them sincerely, makes eye contact, do skinship as possible, and is always open to give his biggest smiles. And did we forget to mention that he once calmed a crying EXO-L who was going through something during one of his solo fan signing events?

4. BTS's Jimin, J-hope and Jungkook

The worldwide superstar, despite their growing popularity way back 2016, humbled themselves as they surprised a family in their flat and even had a chicken party with the high school student fan and their parents. The BTS members even gifted them a dance, seeing her idols perform live. A concert ticket was also given to the student.

5. GOT7's Jackson

The elders visited by the idol might not be fans, but they immediately fell in love with GOT7's Jackson's charms as he surprised a couple of grandmothers and grandfathers in a home for the aged. Even with the age gap, Jackson listened eagerly and paid attention to the elders, as they shared their life experiences and stories. In addition to this, the idol even washed a grandmother's feet, massaged it and held it with great care. His visit indeed made the elders happy, feeling the love of a child once again.

Some fans might feel jealous, happy, teary and will feel moved while watching these videos, but in time, we are hoping that you can meet your idols too! And on a positive note, we wish that you'll be listed as the luckiest fan as well.
