Any romance drama like this?

The closest what I saw is this: Boku wa Mari no Naka , but it is a bit complicated and very psychological. But it is also quite short (8x23 minutes).

 Sechiru:

A female and a male loves the main female lead. Both main male and second female should only love the main female not each other. Do you know any romance drama like this? I want her to end up with male lead.

A strong but immature secondary female character is affectionate with and a bit obsessive about the FL and doesn't want her to marry the ML. The FL ends up with the ML anyway:

• The Legends

The FL dresses / lives as a man (but is a cis woman). A secondary female character falls for "him".  The ML never has feelings for the secondary female character, and the FL ends up with the ML:

• Bromance
• Sungkyunkwan Scandal

This doesn't involve the FL, but Hometown Cha-Cha-Cha has a lovely side story where a secondary female character (SFC) and her husband (HH) reconnect with a female childhood friend (FCF). HH had a crush on FCF, but FCF had a crush on SFC. FCF and HH stay together, but FCF acknowledges SFC's feelings in a kind way. 

There is romantic tension or other romantic chemistry between the FL and her female friend, female rival or other female character, but it isn't really explored and the FL ends up with the ML:

• Doctors
• Twenty-Five Twenty-One
• Search: WWW
• She Was Pretty
• My Unicorn Girl
• Dream High

There is romantic chemistry between the FL and the ML's ex-girlfriend, but the FL ends up with the ML:

• Because This Is My First Life
• Kiss Scene in Yeonnamdong

The ML mistakenly thinks the FL and her female best friend are a couple:

• Her Private Life
