I can tell you that when someone sees their childhood crush after many years, it can evoke a range of emotions depending on their individual experiences and memories.
For some people, seeing their childhood crush after a long time might bring back nostalgic feelings and fond memories of their past. It could be a pleasant experience, especially if they had positive interactions and feelings for that person during their childhood.
On the other hand, it could also be an awkward or unexpected encounter, particularly if the feelings were one-sided or if the individual has changed significantly over the years. Some may feel embarrassed or self-conscious, wondering if the other person still remembers them or if they'll be judged based on their past interactions.
In some cases, meeting a childhood crush after many years might lead to a rekindling of old feelings or the realization that they have both moved on and changed since their childhood days. Overall, the emotions experienced during such an encounter can vary widely, depending on the circumstances, individual personalities, and the nature of their childhood connection.
