break spaces before < *?php the_content(); ?>

Is it possible to modify <*?php the_content(); ?> ? It seems that there is a blank line first before the real entry starts. If it’s confusing, please take a look at https://sacred-tear.net.tc/wordpress. I use text-align: justify with the image-avatar aligned to the left. But the entry does not start in line with the avatar.
Please help. Thanks! ^^
