These dramas both have Nishiuchi Mariya and it shows two completely different personalities by the same person. ( Even if it might not be the real person... if that makes sense.)
Both have the same sense of humour and over the top characters, so if you liked one, I'm pretty sure you'll also like the other.
Sam and his team are members of a Serious Crime Unit in the District Crime Squad. The Team successfully arrests a international crime organization's leaders, Night. At the Court, Ann, a prosecutor and Sam's financee, tries her best to convict Night. However, finally, Night is convicted on only one charge and sentenced to three years imprisonment. Night vows to take his revenge and destroy the couple one day. Ann and Sam take a trip to Paris and the assassin monitors them and kills Ann. Three years later, Sam has escaped to Tai O, a fishing village and a look-alike Japanese tourist named You comes and the romance begins again; however, what Sam doesn't know is the assassin was You.
Both these Japanese dramas are romantic comedy adaptations of popular mangas that focus around a school club. The same actors plays the male leads in both the dramal with both characters being over dramatic in their mannerisms, and fall in love with the female lead from the very beginning but is oblivious. The female characters though played by different actresses have the same personalties of being lonely school nerd until they meet the male lead and then they start to change. As well the girl is also completely oblivious towards her feeling for the male lead.
