I'm pretty sure you've heard of Snowdrop as that controversial JTBC K-drama set during the 1987 June Struggle of South Korea but I'll link to some webpages about it below just in case 
 
Links for reference:

• DramaWiki
• Koreaboo ( 1 | 2 | 3 | 4 )
• Snowdrop on JTBC's official website (it's all in Korean BTW so if you don't speak that language you'll have to translate it into English with some sort of translator   )
• Snowdrop on DramaCool (you can watch it with English subs there BTW   )

My first impressions on Snowdrop: Seeing how controversial that K-drama is I'd probably recommend others (and perhaps myself) to watch it in a neutral light (although since I'm not in South Korea I'm gonna need to watch it with subs on a foreign K-drama fan-aimed streaming website for that  )

Here's my list of 'em:

• Dakishimerarete (TF) - Yumemiru Fifteen (Suma) (especially the instrumental parts and chorus)
• Hitori de (J=J) - Mikan (Momusu) (especially the chorus)
• Teenage Solution (Momusu) - Special Generation (BK) (especially the verses and chorus)
• Watashi wo Tsukuru (AGM) - Ambitious (Momusu) (a lot of it but think of the intro and chorus for examples of the similarities between these two)
• 46okunen Love (AGM) - Romance no Tochuu (J=J)
• Jinsei Blues (Momusu) - Kimi Sae Ireba (Momusu again) (especially the first verse - I mean, just think of the first four lyrics of the former and compare them to the first verse of the latter - I could think about the similarities with the latter in other Momusu songs but I don't want this OP post to last very long so there's that   )
• Kon'ya Dake (TF) - (I'm not going to mention any specific 90s Eurodance songs here but I do feel like Kon'ya Dake reminds me of 'em)
• Wasurete Ageru (AGM) - As For One Day (Momusu)
